i got the set and like it. it is very visible in the city and the headlight is good for dimly lit streets as well. i would not recommend it for higher speeds in total darkness. batteries last surprisingly long and i like that i can stop at any store for replacements if need should be.
there is one downside though:
the first generation shipped had a flaw in the mount for the headlight. the headlight can slip and drop. i had that issue and i'm promised a new handlebar mount by their support department. we'll see...
