my review/BIGadventure with the susie’s 80mw bluray pen purchase!very long to read!

[realista]

That’s my review/BIGadventure with the susie’s 80mw bluray pen purchase.
Hei.. this is a COMPLICATED ADVENTURE…. If you want so see HOW MUCH BAD LUCK can have an Italian laser enthisuast…. Please… read all…. you will not believe what I will tell!!!!!!!!!!!!!!!!!!!!!

The story: some months ago.. I bought from olike, the 120+mw green pen….ok. I received it BUT…it was not strong as labelled(140mw).it could burn something…but it was in appearance similat to my 30mw kaleidoscopic green laser from DX! Trust me! Same beam.. same spot… ok. I sent it back to Susie…and she told me it was PERFECT… good power.. she told me the reason why I had bad power.. is the HOT weather…. Mmhh… excuse me Susie.. but I repeat.. it was THE SAME of my previous 30mw.. ok…..what to do now? I didn’t want to buy the same laser again! I choose a 80mw bluray. .. and I get the refund for the different price. And I told Susie to send me the 100mw version.. at the 80mw price .. : ) ( this…is reasonable.. for the previous problem of the green underpowered, and she accepted this condition.. great support. OK)

She shipped the laser but LISTEN….. it never arrived into italy XD XD XD !!!!!!i waited 2 month about… and nothing… I waited maybe 3 month. in the meantime I wrote to Susie what to do….she told me She has done its job. I understand.. but I never received a laser. That could be DIFFERENT IF the laser arrived to italy… and custom blocked it… that should me a MY problem. But this time… the pack never entered in italy…! She offered me to refund HALF PRICE ..but I didn’t like it.

One day…….after some bargaining..she FINALLY offered me to send again the 80mw bluray laser…BUT this time a real 80mw..not 100mw, and using EMS shipping, that cost me about 24.. 25$ if I if I remember correctly. Ok….she made the shipment and……….woho… ; ( the pack after 5….. 7…. 10… 12 days didn’t arrive to italy (usually takes about 6 days worldwide)… I could feel like? Imagine it!!!!
But this morning….ringed the bells…WOW!it arrives!!! It takes 21 days to arrive!!! And Susie …in the meantime.. repeated me that the laser was with high probability confiscated by italian custom( she told italian custom…block a big about of laser PEN!but not laser torches. But my problem is that I LOVE pens…..and momentary On push button… I would not have a torch style laser with BACK switch… it is not comfortable and safe to use…in my opinion momentary on.. is A MUST in a L.pointer)

This is mi biggest adventure……..trust me… I was really sad… really down .. before to receive the laser. I cannot think.. that firstly I purchase a green 120… received defective 4 me( not 4 susie)..ship it back, buy a bluray.. wait 2/3 months….. pay the EMS shipping( not cheap) for another bluray(the same)…and see that it does not arrive!!!not tracked in italy! Noh… noh… feel crazy!!!!but FINALLY I own a 80mw bluray pen!!!

Let’s start the REVIEW…………..

PACKAGING:
All ok.. a lot of bag….very very well packaged….trust me.

APPEARING and construction
It is a well made pen…. It has the newish style pen…..but SILVER… and not Soft rubber.. justall metallic.this is better that tbber because some months ,.it usually get Scratched.
The only one bad thing is the button… that rattles a lot….but I can’t fix it.. i would not open the diode.

POWER/ BEAM/ divergence
This is my first bluray! I can say that I expected more power from 80mw….(if it is real 80mw.. I don’t have a LPM)…my 30mw green is a lot more visible…ok. The dot is 4 mm wide…..and it is a bit OVAL…… but .. after months of laser pointer forum reads…I understood that it is a COMMON artefact of “natural” diodes… instead dpss laser. In fact also my dilda… do this thing. I think that the dot is a bit oval because diodes give that shape! ( the dot is not REALLY oval.. it is a circle… BUT it has inside a more concentrated oval… I think you understand )

Divergence?...wow….susie told me.. it has 2…2.5 mrad. WHAT? I heard from other member that is really difficult have low divergence with bluray…. But STRANGELY.. my laser pen as an awesome divergence…!!!!!!less than 1mrad(my 30mw kaleidoscopic green). I didn’t count it… but could be 0.6… 0.7… really good!! Why susie told me 2.5 mrad? XD

In the night I CAN see the beam.. but it is wide.. so it less visible than a 1,5 mm diameter beam.. that has more concentrated light. COMPARED TO my 200mw red dilda…. The beam is better visible for me!!a lot better. In reality…I can’t see the dilda beam ….i am myopic!!i am BAD sensitive to red… almost no sensitive to red beams at 200mw! But FORTUNATELY…. I repeat FORTUNATELY… I can see good bluray beam. Ah..and my mother?she is the opposite of me ahahha she see perfectly the dilda beam.. but no so good the 80mw bluray beam! Strange!!!she is miopic like me! I see better near UV.. and she near IR.

I must say another thing…I tried to use a magnify glass and it burns… but not like expected.. mhhh.. it could not be real 80mw… maybe yes maybe not. Excuse me.. but if it is so bright.. how bright can be a 5 mw bluray? Almost invisible? My 80mw does not make so much light around the dot….. I don’t know if it is normal for a 80mw bluray .

Sometimes.. I see DOUBLE dots.. or I I have trouble focusing the dot.. WITH MY EYE….. why?
Only with this color this happens! If I see the dot over distance.. I can’t see it so much… and at about 50 meter.. sometimes I see bad it… like if she makes OUT OF FOCUS my vision….on that point….

GENERAL COMMENTS.

Italian customers are the worste laser enthisuasts….. we have BAD custom…and LONG TIME custom. One for all italy!!it takes 4x times to arrive here packs!!!!
Susie/olike support is great…..even if I MUST SAY…that to have a good support.. i had to break balls to Susie!!!

THE PEN is great… fot 83$+25$shipping… I own a well made 405nm laser…with a less than 1mrad divergence. That sounds…incredible to me!!!no?… I always heard of over 1.5 ….2mrad for bluray… and that they’re hard to own low divergence.
It is NOT a laser pointer to burn….because its initial 4mm beam diameter…but .ok.

NICE to help you…. And thanks to read all my post

I will post some photo comparison between 30mw green and 200mw dilda all at full battery ( NIMH at 1.38v about)
MY PC IS BROKEN....i will post images when it wil be repaired...

 

[styropyro]

It is perfectly normal for you to have trouble focusing on the violet light, everybody has the same problem because it is so close to the end of visibility.

 

[matrixcs]

hi there realista, what an experience you have.. as i was reading it.. i was like whooaa! first of all, im an olike customer too, the first laser i ordered was the 50mw Ultrafire green laser, shipped via DHL, sadly it got delayed due to Susie's DHL agent, i was really wondering why DHL in their location could not get my address well, the fact that RAYFOSS, MAX -UNITE, BOBLaser and some got my address through DHL shipping. Apparently i reasoned out to her that im not living in a City, im leaving in a small town yet, can be serviced by DHL.

after days of debate, i just told het to ship it on the DHL office in a city near me which is about 2 hrs driving.


the laser arrived, really can burn matches @ 50mw, it was rating at 100mw.

but i was wondering after 3 weeks of using it... it suddenly died, I told susie about the situation...and she managed to replaced it...


about your sad experience, talking about chinese BlueRay Pen's.. well take it from my experience with BOBLASER.... 80mw of BR from these chinese manufactures some how willl make you irritated due to top 3 reasons..

1. days you have to wait for it to be shipped
2. divergence and materials used..
3. reliability of their advertised 80mw and so on..


in my experience... i would prefer making my own....blueray pen, have jayrobs kit, get your diode and have a flex drive...

saves more money... and customs confiscation.. lol since it is just a kit they wont confiscate it.

------------------------------------------------------------------------------

about your green laser... well that what i could not believe but yeah.. since it is your experience... im really asking my self how come.. maybe the pen you got is really defective though or your DX somehow emitts brigther than expected....

 

[lasersbee]

Well..... I guess I need to chime in....

@ realista....

1) I sell the LaserBee I across the globe... and if you check my shipping
costs on eBay... you will see that Shipping to Italy(and some others) is the
most expensive..
There is a reason for that.... On numerous occasions our packages did not
get to our customers... Now we send them with the most expensive service
and they DO get there.
There seems to be a problem with some country's Mail Systems...

2) Do you have a Laser Power Meter....??????

3) If you do not have a Laser Power Meter your power statements are all
subjective... maybe with my eyes I would see different results..

4)For divergence measurement were you using Laser safety Goggles of the
correct wavelength..

5) If not... your divergence measurements (which I have seen do data on)
mean very little (I know because I have done Divergence measurements
with and without Safety Goggles and the results are NOT the same)

6) your statement about Susie and your Balls is quite INAPPROPRIATE

7) I have personally Never received an under spec Laser from O-Like to date

8) I would suggest that you get yourself a Laser Power Meter to substantiate
your claims... eyes (as far as I know) are not standardized...

Jerry

i agree with jerry, I checked with a friend of mine who lives at Italy now, she told me your customs there are so corrupt. Not to mention a poor local mail service you got there..

better send a package using expensive one..


btw.. realista... is your eyes not sensitive to green??

i heard from susie you got that problem...

so i guess you better buy a laser power meter...

because the eyes can be deceiving...

trust me..

 

[realista]

@matrixcs

i am sensitive to green....good sensitive like almost everyone my problem with the previous 130mw green laser from susie... trust me.. it was real.. excuse me.. but if you ask everyoneto compare the brightness of a 30mw laser VS a 130 mw laser... is there a difference? i think yes. with the susie laser.. not. i am not saying that susie don't sell good lasers.... but that in my occasion...i received not a 130mw laser... but about 50mw i think!...or my DX 30mw laser is really a 130mw true?i don't think

YES...i need to buy a LPM... but for the moment i have no job....;( i am doing a course to work in hospital assistance. in next week i think i will purchase che little lpm from laserbee.. this is the better lpm that i can buy now. however.. if my laser is 80mw.. i can't imagine how could be a true 5/10mw bluray. i am luck that 80mw bluray is USABLE...and sufficiently visible in the night ..with a "decent" but dim beam. when i will have more money to spend.. i can ASSURE YOU that i will purchase ( but i hope do it MYself) an over 500mw bluray.. i want a class4 laser but green..are so expensive to have class4....and.. i am getting in love with this new color (violet) ...i like it. the oly problem is that i see th ebeam but not the SPOT over distance.

@lasersbee

i understand what you say. but about divergence... trust me... i see the truth. you could think..WHY? i get a lot precise measurements of dvergence BECAUSE i have in front of my house...a seaport a good wall situated at about 650meter... checked with google earth meter... and can see people what walk on. this mean that i can calculate a VERY VERY precise divergence using that distance my DX 30mw laser caleidoscopit is 1mrad +1/-1 and this bluray...is about 1/4 or 1/3 of the diameter of the green i can ASSURE that my laser has 0.5 mrad or lower...maybe 0,4. ...0,3mrad.(i use binoculars to see the dot at 650 meter)
LITTLE UPDATE.....the laser has a NEGATIVE DIVERGENTE ( that's good!). it starts at 4mm then.. at about 2 meter it is smaller... then... increase. it does not burn so much at the focus point.. but.. for sure.. it is a PRO for a laser pointer....it has very low divergence. .and also a focus point at 2 meter.
_______________________
now i ask you a suggestion: can i use a 10440 lion ?i remember susie told me that it is possible... and that all laser pen are tested with fresh alkalines .. to have the listed power. but i cannot understand WHY aaa laser pointer use 3 volt. we should be more ecologist-----and safe money. i think everyone use nimh batteries... not? the problem is that they are at 1.4 fresh .. but quickly dop at 1.32... but for MOST TIME they settle at 1.28/1.27 volt.
ok....no one can see by eyes 30/20 mw in less. but it is no a correct thing to have a laser lower in power than advertised.. only because we use nimh.

i've never inderstood if is safe to use a 10440lion that peak 4,2 volt in a laser pen designed for 3v. but i ask MYSELF.... is REALLY the pen diode designed for oonly 3volt? please... let me know a method to understand if a driver/or/diode requires 3v or 3.6 v. how can be it checked?

i know duty cycle is lower with more voltage..and the laser gets heat in less time. but i think that also susie is not able to tell correctly me if my 80mw laser is REALLY construpted to 3v or 3.6. but everywhere i see 18650/cr123 lasers..... i i think that the most laser requires this voltage.. and that the producers of PEN lasers...put this diode and driver in a small host.. just because people like me...prefer slim and long laser... NOT THINKING THAT using 2x1.5v or 2x 1.3v are optimal or enough to power the laser.

this is my reasoning..........you can share or reject it

 

[Fortyfive]

When I read this:

Susie/olike support is great…..even if I MUST SAY…that to have a good support.. you have to break all balls to Susie!!!(she is female.. but I think I gave her 2 BIG balls ahaha)

I just about died laughing. This could be the funniest post I have yet to see on LPF. This is a must add to the compilation Niko! Thanks for making my day Realista, when I buy my new style dilda I'll be sure to " break all balls " to Susie.

In all seriousness though good review minus the inappropriate comment. Blu-ray is a strange wavelength, looks weird to your eyes, and its not very useful for pointing. Its meant for burning.. The larger beam diameter allows it to be focused to a smaller point using a lens, thus why so many members build there own using aixiz modules with an adjustable focus. Even an 80mW blu-ray can be a nice burner when focused properly. This can be done in pen styles as well, check what RA_Pierce did ( I believe thats who did it ) with his beautiful pen style units he was selling. If Im wrong on the person Ill edit my post.

edit: I was right on the person, and I found the link to the pen units. Check these out realista..

[realista]

thank you very much 4 the link . i think every bluray laser pointer has a wide beam-... is it ossible to have a beam like a green laser? about 1/2 mm? i think it is impossible.... but yeah...with a wide beam is possible to have less than true 0.5mrad... and this is a nice think for me. i can shine my 80mw bluray to the seaport at 650 meter ..and people can see the violet dot.

but if the laser had a divergence of 1 or 1.5 mrad...it shouldn't be possible to see at distance.... violet is just DIFFICULT to see and focus by eye(i see only beam sometimes)...plus if it has bad divergence... it is USELESS i don't know why susie told me that it has 2.. 2.5 mrad before to buy it. i thought it was a normal thing ... that is difficult to focus blurays...

I will post some photo comparison between 30mw green and 200mw dilda all at full battery ( NIMH at 1.38v about)

Ha, sounds frustrating, yes susie has great customer support, I badger her everyday almost on MSN. I feel your pain, Australia has strict rules of only 1mw lasers. how fucked up is that 1MW. anyway i ordered new 100mw focusable bluray torch. she disasembled it, relabled it as flashlight repairs and in 6 days arrived!!! sorry to here your news. Also yeah, the beam when you shine it in sky gets really thick really quickly, it spreads out really quickly, a bit dissapointing but mine burns quite well.
If you have anymore news please let me know and good luck for future buying!

 

[Alexie]

what do you mean by it is hard to focus cause it is on the end of visibility!?!?!

 

[styropyro]

what do you mean by it is hard to focus cause it is on the end of visibility!?!?!

Violet from blu-rays is so close to the end of the spectrum of what our eyes can see, so the dot will look very blurry. If you look at the dot from 30 feet away it will look like the dot isn't focused right and will look big, but if you walk up to it you will see that it is small. Because of this it is impossible to distance point with these lasers.

 

[Grix]

I'm sorry if I sound rude, but I don't really know if I can trust your divergence calculations. You seem to report amazing divergence on all of your lasers, I read that you said that you dialed you dilda down to 0.1 mrad, it doesn't really sound right to me. I would say looking at a dot through binoculars from a long distance is a very inaccurate way of calculating the divergence.

 

[realista]

grix... this seems to be strange.. but my calculation are accurate. i don't trust who calculate divergence over 10 meter... 20 meter.. 30 meter. . for me it is a little ditstance to reduce the ERROR calculating. intead.. i use 650 meter... or also another wall situated at 100 meter...

why don't you trust on my readings? i received a 120+ olike green laser pen.. and the divergencewas worste than my 30mw kaleidoscopic.. that has about 1mrad.

this 80mw bluray.. is wonderfull in beam spec.... has the focus point at 2 meter... aand the dot is very very little over distance. it is incredible but true. the dot is 1/3 or 1/4 of the green 30mw. ok it has 4mm initial beam diameter.. but i can assure you it is about 0.3 mrad . i don't know how compare it in a photo to explain you .i notice that over distance the dot is NOT a PERFECT circle/oval.. but i think it is because lense is acrylic/plastic. i don't know of could be possible to change it with a glass lense... to have a better rounded and precise dot.

"looking at a dot through binoculars from a long distance is a very inaccurate way of calculating the divergence"
i can compare the dot with the human body of people who walk on the seaport... if the dot is about a head... i estimate some centimeter.. if the dot is like a men with OPEN hands at "X" .. i calculate... and the good thing is that 650 meter is a big distance.. and the readingd are less influenced by other factor..

Hi there, did u say the 120+ olike pen had bad divergence as i am looking at one, is it worth getting?

 

[realista]

it has a normal divergence.. i think good. it is A BIT less focused than my dealextreme 30mw kaleidoscopic... just 0.1 mrad plus i think. be sure that you receive a good powered mine. i was bad lucked... i received one that was visible as my 30mw. susie told me it was ok... i don't know what to think. now i have bluray.. and it is a nice color.. and seems that i am GOOD sensitive to violet more than my parents... that prefer and see better red beam of dilda.

EDIT. i ask to all readers... one question: is NORMAL that if i use a 10440 lion battery i can HEAR a little noise when i put the hear near the laser?it makes a bit of noise when i press ON..... i am afraid this could break the laser.... so i continue to use nimh rechargeable batteries...that does not procute sound/noise.

baybe it is a normal sound produced by the potentiometer or somewhat....but i wait for some specialist member

 

[matrixcs]

nope just use a good alkaline battery on your pen laser..
