I tried one of the key chain green lasers from Screambuy.com...
I am very impressed by the power and stability. Especially for the size!
Here's the link:
532nm green laser pointer in key chain style [532nm bgp-3009 key chain] : Screambuy electronic consume products
I chose the 20mW one (less than $20 bucks), and asked for a nice stable one.
What I got was a very stable 44mW key chain greenie!
Then I modified it to fit a 10220 battery...
I tested the power with the LR44 button cells as well, and it was the same with the button cells, as it is with the 10220 battery.
That means that the driver on this module is regulating very well.
Just thought I would do a short review on this key chain, because it is so nice and stable. Hopefully they are all like this one!
P.S. The clasp shown in my picture is off of a different key chain light, and the sticker is one that I put on there as well. It comes with a sticker and a clasp, but I changed them to ones that I liked better. (nothing wrong with the ones that it came with though)
