It's a great idea and if it had a master on/off switch I'd probably like it very much. As it is, any light touch will turn the laser on so you couldn't possibly carry a pistol with the Genesis mounted on it. I tried putting it in a small pouch but after carrying it around a day or two I took it out to test it and the battery was dead. I guess if you could leave it on the charger and ask an intruder to hang on for a minute while you mount your laser it would be pretty good. When it's charged up it works very well. Too bad every little touch to either side activates it and eventually kills the battery.
Pros: Easy to mount and zero, lightweight, and it's a niceand bright.
Cons: Too easy to accidently turn on.
