The quality seems nice and robust. It came with batteries inside the tube (I first thought there where none because of the empty package). It worked right away.CON: There is no on/off function. To turn it off you have to unscrew it from your bike - every time! This is pretty bothersome because You can't leave it on your bike.. I took it for my mom but she can't really use it because she can't screw it on nor off every time she uses her bike.

I have bought my second pair of these as. The overall effect is cool, draws peoples attention. The sensors (motion+light) work amazingly well. The lights switch off quickly when you are done cycling. The provided battery lasts for approx. 25h of constant operation, for me this meant 3 months of cycling 5 days a week with the lights working for 25 mins each day.

Suggestion

There are two major issues with this product: 1) The instruction asks to attach a small spanner for the narrow road bike valve which are not provided in the pack. This causes the valve to slowly unscrew from the rim (BUT NOT release any air from the tire) which means that you have to tighten the valve every week or so. 2) The light quality varies a lot. I have bought two white lights of which one shines yellowish and much weaker. Despite these cons this is still a very fun and somewhat useful gadget which is fun to watch. Definitely worth a try!

Attaches to my valve with no issues. Bright color. Displays patterns as shown. Must go FAST! downside, buy two as it only comes with one light.....other than that, great value!

Una luz para la rueda que da mucha visibilidad cuando circulas, se enciende sola por el movimiento y cuando no detecta luz, el peso es insignificante y las pilas duran, llevan puestas 6 meses y siguen.Cumplen con lo que quería.. que me vean, ahora se me quedan mirando !!! Eso si no es para nada como sale en la foto,

Simple to install. Just remember to remove the battery guard before use. Lights up well and makes it easy to be seen from the side when riding at night.

Suggestion

The only downside is that these aren’t really viewable from the front or rear.
