As the most recent Lighter-S trouble topic, I thought I'd BUMP this thread to report that both I and ex-workmate Eddie have been having problems with our Lighter-S tracer units.
Mine is still stroppy. It will sit ostensibly charging for many hours, but then if you disconnect and reconnect the charger, will show as full. It requires several on-off cycles before it stops flashing red error / bogus low battery, even when freshly charged. Once it's on, it will stay on, but the intensity has dropped off significantly since I first got it (with both ASG blasters and AirsoftWorld green tracers), leading me to suspect that some of the LEDs have failed already.
Ex-workmate Eddie dropped his Lighter-S and wrecked it, so had a brand new one on Sunday, freshly charged, and functional at home. On site, it failed immediately, ostensibly turning itself on (green light flashes) but then it wouldn't turn off, and didn't function at all.
I really couldn't recommend them. Nice idea, but the quality is shoddy even by airsoft toy standards.
