This is my review for the LZSK Stick 1W 445 by lazerer.com: http://lazerer.com/lzsk-stick-445nm-1.2w-focusable-blue-laser-pointer

Processing and Shipping:
I placed my order on the 25th of November, and bought two of these stick lasers, one for me and one for a friend. I also bought the charger, batteries and power certificate. I have written in the comment box, that I will be doing a review, and that i would be happy to receive over spec units, if he has some.

About two hours later (26th of November, because I placed my order late in the night) I got the paypal request. The morning after I payed, and another few hours later it was updated to processing.

13 Days later (9th of December) my order was shipped, sadly without the batteries because of the new precautions by Hong Kong Post. Here is the notice from Max:

The comments for your order are:

Unit ready, awaiting for shipment

Due to the new precaution taken by Hong Kong Post. To prevent the delay / loss of your order so far we cannot ship the li-ion battery. Please refer to the notice released by Hong Kong Post below:

Hongkong Post - Notices - Delay In Outbound Air Mail Services

we are so sorry for the inconvenience


It took 3 days to arrive to Switzerland.
It came in a nice cardboard box with a magnetic closing mechanism, and is quite usable for storage.

Conclusion: 13 days processing is not that good, but it may be due to my special request. Anyways 16 days in total is very fast, so it`s still a 10/10

The Laser
I asked for overspec, and hoped for a few milliwatts more than they state. Because only 950mW are guaranteed I expected maybe 1010 or so. I was very happy when I saw what I got: one was 1141mW and one 1151mW.
Actually I only bought it for burning, and didn`t expect it to give a spectacular beam, because according to laser visibility calculators my 532 should be brighter than the 445 when viewing the dot. It is true, that the dot is not brighter than my 50mw green, but the beam is. In fact it is so bright it makes my green look really ashamed :) but see for yourself:

Actually the green beam IS visible, but my camera doesn`t pick it up quite right. But the dot brightness is quite authentic.

The laser doesn`t look exactly like the picture on lazerer.com, but it looks nice.

Here you can see the diode in the heatsink which seems to be brass and does the job very well. 45 seconds on, 60 seconds off seems to work well without overheating, underwater you can use it for much longer of course.

Also one little issue I had, was that on one of the lasers the focus was stuck. It took quite a bit of force to get it to turn (vice + piece of cloth). But now that it is unstuck it turns very smooth.
Because it is sealed with O-rings it CAN be used under water, but it will get out of focus if you don`t add a piece of glass in front of the lens. Also it is not 100% sealed so after about 15 minutes in 1-2m depth I had two drops of water inside.
With the acrylic lens that is inside the output is perfect. No wings and no "splash", but 3 days after buying it I managed to get plastic smoke on the lens which killed it. Now I installed a AR-coated three element glass lens (I had to sand it down a bit, because it is 0.5mm too big, but it is doable) which gives me the typical wings...
Conclusion: 10/10 (I don`t see the acrylic lens as a problem, but you have to be careful)

Here just some additional eye candy; 1151mw of blue + about 400mw of green (8 * Laser301), makes me want to have that color in a single unit :rolleyes:

Can't see the pictures but wow. I don't know if I would have tested submersing it for so long, but it looks like it survived so good for you :)

Glad to see you got some overspec units. Does the three element give you any power difference. And for another 25-30% Increase you could always swap it for a g2-1-9 lens.

Nice review, just wish I could see the pictures.

Now I fixed it, somehow the attachment links are "local" before publishing the post. So it seems like I have to always edit!? You should be able to see them now.
I don`t know if it gave a power boost, because I don`t have a lpm yet.

I can see them now ;) and I would think it would give a power boost. Unless I'm mistaken, I believe the acrylic is the low end of the lenses when it comes to power.

No. That means all lasers are ready and in their shipping package, but they didn`t yet give it to the carrier!

Ohh? Well I hope it gets shipped soon. Have you had successful orders from lazerer in the past recently?

No (except of course the one I`m reviewing here), but if you did a forum search you`d know, that Lazerer seems to be a honest and good quality seller.

Really? Has this changed in these few months or what? Because when I ordered I only did because of the good reputation here.

I have a question for both RGB & Tmack I'd like to ask. RGB, I've read your review of the Lazerer 1W LZSK Stick, as I have been interested in this laser. I currently own just 2 units from Lazerer. A 50mW Green Classic 301, & 200mW Red Cyber with adjustable focus.

My question is regarding replacement lenses for the Cyber 650nm focusing portion. The collimating lens is frosted & the 9mm is broken. I see where Tmack mentioned DTR G2 3 element lenses, but do you know if this focusing lens from DTR Tmack can be screwed into the focus adjusting ring that mounts on the host body next to the laser diode?

And where did you purchase your acrylic lenses RGB?

I need any help or suggestions you guys have, to repair what is damaged.
