Bought two 210 sets for my wife and my front tire and two model 232 for our rear tires. After first tire installation learning the rest went on pretty easy. Wife's 210 stopped working and after changing plugs, batteries, and the troubleshooting ideas still doesn't work but we get a ton of comments about them.

So it has 2-3 different levels of brightness, with all of the themes they show on the manual and on the website. However, I cannot get it to stop automatically transitioning the theme. It includes a theme button, but this only skips the current theme, continues automatically transitioning themes. Some people also say that these lights are very distracting to drivers on the road, which is one thing that I did not think about when I ordered them or at any given point during the shipping process. It has become apparent that they did not think of this either. Other than those things, the product works excellently and is completely resistant to water, which is something that I very much appreciate, living in the Northwest. I have been using this product for about a week now, and have run into no issues.

These are fabulous! My daughter rides her bike to work....8 miles each way in busy Portland, OR and it's dark now. She said for the first time at a particular intersection, cars are now stopping for her. Many people roll down there window and compliment how easy she is to see. Very bright and it would be impossible to miss her coming down the street. They are also very interesting a beautiful. GREAT idea. I feel much more comfortable that she is as safe as she can be sharing busy streets with cars, motocycle and other bicicylists. MARVELOUS PRESENT for anyone you know who rides there bike at night!!!!
