The lights themselves are quite OK for the price, but there is a serious design flaw: the rubber flaps that guard the USB ports are narrow, flimsy and easily broken off (I managed to break one while pulling the light from the USB cable...), and then the ports are exposed.
Too bad, because the mounting straps look super strong, battery life is good.... so this would be a very nice commuter light set, if not for the flap... Now it is hard to tell how long they will function, they could be damaged after the first rainy day.
