Review on Enhance safety on Busy Roads with Cygolite Hotshot Pro-150 Lumen Bike Tail Light: 6 Modes, Customizable Flash Speed, Compact & Water Resistant Design, USB Rechargeable & Secure Hard Mount by Dave Hock

First flashlight was great out of the box and after several rides. Then he brought it in to charge one night and it wouldn't turn off, didn't respond to most button presses, wouldn't turn off. I ended up thinking it was off and it must have turned back on and drained completely. I'm glad I had a spare with me as I had a dark drive home. I'm coming back and I hope the second one works well because it was really great when it worked. ---- Update ---- The second one arrived very quickly - thanks Revane, unfortunately it quickly started showing the same problem. Turns on randomly, doesn't turn off. The buttons are clearly not glued, the light has not fallen off or been otherwise treated. Tried charging, no improvement. Unreliable junk at the moment. I contacted Cygolite directly about first light and received no response. Tomorrow I'll try to contact them by phone to find out how things are going with these bright but moving brands. Too bad because it really is a great light when it behaves. My old Pro 50 never had a problem. ---- Update 2 ---- I worked with Cygolite to get one of the faulty lamps. They sent it back maybe a week later with a little note that the circuit board had been replaced. A few weeks of use and the light works well. I still don't trust him 100%, but he behaves without any problems. Maybe Revane got a bad batch.
