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

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.
