Your right Lase, thanks that is a really good idea and I bet it would make what I am trying to do a lot easier!!

Finally figured out how to take a bit better picture to compare the beam size of the O-like's beam expanded 100mW 532nm. This is next to a 30mW Newwish 532nm. The camera is about 2.5 feet away.
It's a lot easier when you don't have to hold the laser or the camera!

Now that is A LOT more interesting.
Hmm... if they come out with an at least 200mW model... I'm down for one.

Well I FINALLY got my laser in the mail today. I guess they no longer have those white laser boxes. They wrapped it in bubble wrap and put it in a small brown box this time. It actually works too. Of course I cant take any pictures since my phone broke and my current blackberry doesnt have internet 
I can say with 100% assurance that I will never endource or buy from O-like again. They are still denying my refund for shipping. Now they are telling me there is something wrong with their paypal and to wait 2 weeks.... By that time the 45 day period will be up and there will be no way I could get my refund if they dont want to give it.

Yeah, I can imagine. I just got a watch today from ebay. A specific model I've been after for a long time.
Listed as 100% functional.
Of course it doesn't run. Looking at the pictures in the sale, the second hand is in the same exact position as it was when pictures were taken. I'm giving seller 24 hours to respond, after that dispute and negative feedback.

holy crap, that sucks! I just dont get why people have to practice such shady business ethics. You would think common sense would tell you the better you are at pleasing customers the more money you will make. Hope it all works out for you.

Thanks, and I hope o-like comes for you too.
Funny thing is, I also made a bid on another watch... it was a long shot... and won.
For what I paid, it FAR surpassed my expectations.
I don't really get it... I mean do people actually think buyers are willing to just sit quite while getting ripped off? Especially when means for recourse are readily available.

Hi,
I am looking at getting one copy too. The photos look promising. I presume it should be able to hit between 5-10km no problems. (aided with binos).
I emailed them and asked if they would be kind enough to test before sending it out. Shipping to CN/HK is not that expensive, I have shipped a Fenix TK70 there for exchange and it costed me about usd19(S$25) for that 1.4kg package. I checked, if i send it back in a small padded envelope it would be just under usd10 for everything. But of course I’d like to get a working copy the first time round.
I have purchased stuff from them before and its good…. Bubble pack in brown box.

Got my copy, asked them to omit the Ultrafire 18650 as i have tons of such cells from my flashlight hobby. It came with a charger. The only decent budget 18650 is the Trustfire Flames 2400mAh protected, its very well tested and used real life at CPF/BLF.
It was inside a holster and wrapped in 2 layers of bubble wrap so that is definitely enough packing and protection. I told them to ship in a brown box just in case.
Interesting beam. the feeling is that it is an XR-E aspherical LED flashlight with adjustable focus. Same amount of light but in green. I don't have a LPM but i have a lux meter. Unfortunately the lux meter has different sensitivity to green. I'll see what i can do. The focus is "adjustable", you probably can focus and put a 50cm wide spot on a target 3km away.
Lets see if i can get any beamshots and see how's the attentuation of "100mW" of 532nm over a few kilometers (unfortunately I don't do astrophotography, else i could take some real far pictures).

Ok, some readings. SD-302 532nm gave 3.6 lux on the meter in a ceiling bounce on my light meter, current is 0.35A. This is 5.7 lux, 0.48A.
Measured with both Sanyo 2600 unprotected and Trustfire Flames 2400, same 0.48A. Uni-T UT58E with short 4-inch 18awg leads.

Laser pretty stable, some very very minor mode hopping detected only.
This laser throws quite far but you'd have to use a pair of binos in one had to assist your vision and thumb+index finger on the other hand to adjust the head to fine tune the spot on a 4km target.
The focus is quite fine fortunately, because on such far targets you'll need that finesse!
Had a good day of fun on it, managed to run down my Panasonic 3100 to flat so that's some 3-4 hrs of total run time.

I managed to drop the laser and knock the "KTP crystal" out of alignment.
I put quotes there, coz the crystal is held into place by a big piece of circular brass "pill" that you see when you take off the top. The crystal is held into place with some white thermal glue to the brass pill with that small white plastic lens holder + lens into place.
So i just scraped off the thermal glue and reglued it. Of course careful alignment is needed for it to lase at full power, but not a big issue.
I managed to make it lase straigh, so that the uncollimated beam now hits whole part of the front external lens. Nice.

I am taking tacoherder's pictures. Basically it's an easy job, reapply some thermal glue, put it back in, make sure it lases straight (You'd know that easily because it'd be fully power only when it is really in place, very very minor adjustments after that).
Basically you'd want that green KTP crystal to be in line with the 808nm pump diode that you see at the very end of the wire and the diode seems to be strapped to that small copper "heatsink". It is not difficult.
