Customer Reviews

The green laser doesn't work well with 1.2V per cell from NiMH rechargables (or semi-depleted alkalines). With 1.5V per cell from fresh alkaline batteries, it's consistently and properly bright. At 1.2V per cell, it's sometimes bright, but often dim, and weirdly variable from click to click.
The purple and red do just fine on 1.2V per cell, so you can move partially-depleted cells from green to red/purple as they run down, or use NiMH in the red and purple (eneloop NiMH AAA are good).
These are powerful enough that it's worth reading the class III laser info on wikipedia. Any more powerful and you'd apparently need laser goggles. Don't assume they'll be good presentation pointers unless your screen is a diffuse reflector and your venue is fairly large (or maybe a filter cap from another pointer would fit). Avoid playing with cats with these - I think they could actually damage the cat's eyes, or at least make the cat suddenly very afraid for a disturbingly long time (based on seeing an incident with a lower-powered laser hitting a cat in the eye).
The purple one can charge glow-in-the-dark stuff very quickly, and the re-emitted light while it's charging is in the same league as the green.
The red laser is bright, but not as easy to see in the air as the green. It's best trick is it makes you feel good about having three choices.
UPDATE: I also got the separate green laser and separate purple laser also from qq-tech, with the diffraction tips. As far as I can tell, the lasers in this 3-combo aren't compatible with the diffraction tips (well, you could tape them on, but no threads at the front to screw them on). My two green lasers are still working.

product was great it works just like they promised i love them. the red is bright the green is bright the blue/purple is bright but its got a star tip not just a dot.
