Muy buena calidad y ejecuci¨®n

What a great tail light!

I have been through several tail lights trying to find one that just works with no hassles. This is it! I had it for about a year now and I have had zero issues and I have only charged it twice. The brake light works perfect. I use this light on a folding electric bike and it takes a lot of abuse, The light is still hanging in there.


Completa mente de mi agrado en cuanto a materiales se ve de muy buena calidad, cumple con los requisitos. Recomiendo al 100%

Very good product

easily installed wherever I need to. Great battery life, charges quick

Better then expected

Compact & powerful bright light with various modes! A smart light that flashes while I ride and can tell when i brake ( brake light). Easy to install and very worth it! Good find/purchase
