I ride in Santa Catalina foothills, during the day. Wanted drivers to see me. The taillight, in particular, is the best daytime strobe I've tried -- and at about $40 during the sale, price could not be beat. A single charge seems to last about 50-60 miles on the super bright flash mode, or about 4-6 hours.
These lights are bright and helpful for riding in low light conditions. The rear light does not attach well to the back of my bike when I use attached bike bag. Works better without bag being in place.
They work great during low light hours.,
