Here's a short video I took with the lasers. I don't know how useful they will be for anyone, but what the hell. Taken with my Galaxy Tab 10.1.

I just bought this 3-pack and I can say they are wayy over-spec.
I have a rayfoss 50mw green laser and it is very uncomfortable to look at without eye protection.
I have them all running with Energizer rechargeable 1.2V NiMH batteries. So they'd probably be even brighter with Alkaline 1.5V...
