Review on Stay Safe And Visible Anytime With GPMTER Ultra Bright USB Rechargeable Bike Tail Light - Perfect For Road And Mountain Bikes by Mahmut Ojeda

These red bike lights have been working well for me so far. I don't use them that much. So far I have recharged their internal batteries once. They are very light weight. And their light seems to be quite bright. They have about 4 or 5 light settings, flicker types, cadences, etc.The rubber band strap they use to wrap around objects is very soft and stretchy. I have a feeling in the long run this will be the weak link of these lights. But the strap does feel like its made of durable enough material. Time will tell.I don't know exactly how long they take to re-charge or to discharge as I left them to charge overnight, and I use the lights on relatively short bike rides, once in a while.It has not rained while I rode the bike with the light on, so I can't vouch for their water proofness.
