Once the flashlight turned on and never turned on again. I thought the remote didn't have a battery. I changed the battery but nothing changed. The remote probably doesn't send a signal and therefore doesn't work. I spent about an hour dealing with it... I'm throwing it in the trash.

It was used on a bicycle and what I have to say is that it is an incredible product and value for money. Easy installation, impressive light both during the day and in general, my overall experience so far is excellent. I recommend it!

It was installed on the front side of my Mi3 scooter.
The light on the handlebar column (patented with a hairband) and the controller on the handle. Very practical, nice, necessary for safe movement, with immediate response in every function and with intense illumination. It charges with microUSB, lasts for many days.
However, in my opinion, the option of red-blue strobe should not exist. Nevertheless, it is very good.

The battery lasts quite a long time.
An excellent product.
A valuable and very useful gadget for cyclists
