EXCELLENT device!! Shockingly bright even in full daylight and has impressive battery life. Up to 16hours of claimed run time (depending on mode) seems to be entirely realistic. It comes with multiple mounting systems that should satisfy any style of bike. My bike is an uncommon modified Grizzley and it was no problem to attach the mount in just a few minutes. The mount sports a super positive twist to lock "click" and there is absolutely no play whatsoever. Two hours to charge from dead flat to full charge gives a rider many days of operation, especially when using the auto on/off modes. The accelerometer activated brake light works exactly as advertised and is unmistakeable by following traffic. One reviewer complained that there is no way to know the charge level but that's not the case in my experience. The unit maintains a super consistent brightness until its approaching "need to charge" level. It then shows an OBVIOUSLY lower output long before it quits. One only needs to have a general awareness of the last time charged and a visual check once every so often. While charging it lights up until full, then shuts off. For such a tiny device the brightness and visual impact is truly impressive! I have vehicles but I use my Ebike as primary transport as much as possible so safety devices like this are always on my radar and this one is definitely a keeper! I can't imagine why potential purchasers could possibly want more features from something this effective and at this price point. Clearly, I am a very positive customer. for this product.
