Questionable quality - Beamshot Tactical GreenBeam Waterproof Laser Pointer

I've got a Beamshot weapon light that I've had for years. I needed a good pointer for work. So i bought this one. Started out great. Then became intermittent. Now, doesn't work at all. I didn't beat it up. It still looks almost new. And, no, it's not the batteries. I wish it was. Now I have to find something to replace it with.
