i bought them, they were horrible. poor built quality and the mounts snap off so easly, even if your gential with it. it produced very little light, might be fine at night in good weather with steetlights. but in pitch black nights, poor weather, long distance or with fast moving cars on the road just save your money and buy something better. get a Q5 or a P7 light on deal extreme(~20/40dollars) and get two planet bike super flashes. that light on ebay is the bear minimum so i cop doesn't pull you over, but it has poor visablity and won't save your life. also it will break or stop working after six months.

your bike and life is worth more than 3 dollars and 38cents. imo spend at minimum 40bucks on lights, but you can be a good set where you can both see the road be seen for 120dollars and an even better setup for 150bucks.
