Bests & Worsts Reviews from Amazon

Out of the box - 5 stars - appeared to be well built, solid, bright. Week 1 - 4 stars - two little annoyances cropped up: 1. The light comes with rubber grips to go on the handlebars. They grip the handlebars just fine, but the light collar doesn't grip the rubber. A little work with some sandpaper to roughen up the plastic and all was OK. 2. The light has three modes; High, Low, Flashing and one button. It always turns on where you left off, so if you want High (like I do when using as a headlight) it takes 5 button presses to turn it on - On Low - Off - On Flash - Off - On High. And if you forget where you are, start over again. Much prefer my Petzl that has the same modes, but always comes on in High, then allows a mode change with a single press within the first 10 seconds. Week 2 - 2 stars - Starting in the second week the light started to either change modes or turn itself off when riding over bumps. This is a road bike, only ridden on paved roads, but there are still some small bumps. The light would suddenly change from High to Low, or Low to Flashing, or maybe just turn off. Major pain in the a**, especially when you're working hard and don't have a free hand to go through 5 presses to get it back where it started. Week 3 - 1 star - Going over one of those bumps the lens popped out of the light. Now I have a dim 120 degree beam that is pretty much useless. Maybe still shows oncoming cars that I exist, but otherwise not worth the weight on my bike. If this had happened at a year maybe could have accepted it, but at three weeks not worth the money I paid, even if that wasn't very much.
