ksyoungA great and extremely bright bike light that is definitely worth the price. Enough to light you way and/or make you visible to cars. Attaches/detaches to the frame in a few seconds making it easy to stick the lights in your pocket when you park your bike. USB charging means never buying batteries, and the charge lasts well. Commuting 40 min per day I recharge the head light about once per week and the tail light half that often.
I've had one set for 2 years with no loss of performance, just bought another set for my wife.
