Light & Motion Vis 180 Degree Commuter Tail Light

I believe the Vis 180 is a neat light, but I am disapointed with it. I just received my light this week and have used it on two rides totaling 55 miles. I charged the light after I received it and before I rode with it. However,the charge light indicator went to red before 50 miles and I felt the blinking red light was so so. My Planet Bike Turbo is far superior. It stays brighter and flashes for way longer periods of time. I used the Planet Bike last summer on a cross country ride and changed batteries about every two week. Daily run time on the Planet Bike was 7 to 8 hours per day. The Vis 180 will not come anywhere close to that performance. For me, save your bucks and buy a Planet Bike Turbo
