When It Works, It Works Well. Update! (How to fix if it keeps shutting off randomly.)
Update: after having a pro resolder the board, turns out the 18650 was faulty. If you're having issues with it shutting off randomly and all the wires are intact, replace the 18650. After doing so its stayed on even after hitting potholes. Original review: I've used it for a few rides now and it's a nice taillight. I ride in a very remote place with few streetlights and cars have been able to see me and act accordingly. But I've come to learn the wiring is seriously faulty design. My battery connector was so lose that if I moved it slightly it would shut off. Not fun to learn at 1am 16 miles away from home. And even after tightening it up it still seems there is a faulty wire that with the right amount of force (like a pothole) can shut it down. It's shaken my confidence about how well it can perform but I just make sure to keep a screwdriver on my rides now incase it ever acts up. Definitely test it out before taking it on a long nights journey. I'd rate it 5 stars if the wiring was better and if you don't want something you might have to mess with, I'd look elsewhere.
