I have used solar tail lights by this company for 10 years...and only replaced one after 9 years of use! The taillight is identical to that original. Bright, holds a charge for a decent commute ride, and holds out up to weather pretty well (I commute in winter in the midwest, so cold and snow are the norm).The headlight is WAY better than the one I bought 4 years ago. Really bright, hi/low/flash modes, and pretty sturdy build. These are not built like the aluminum-bodied high power sets for $80+, but they are good quality for price. I wouldn't use the headlight on a deep woods night ride, but for commuting and casual transit, it's amazing for being seen by others and casts great light for potholes/frogs/armadillos or whatever your local native nighttime obstacle may be.
