It shines brightly for the money; it’s so cheap that it’s worth buying 2 to 3 pieces to have on hand. I don’t know how long it lasts, but it lasted me for a few rides of over an hour each, and then it asked to be charged. I cycle now and then purely for exercise, and it looks very bright on the road; it’s easy to see. You can put two together on the seatpost, or put two on the frame to shine—one on the right and one on the left of the wheel. Nice idea I gave you, huh? Now I’m going to buy a rear light that shines with a G-sensor: as soon as you press the brakes, the light detects that you’re braking and turns on automatically, with no wires and no time-consuming installation. It’s this one --> Rockbros TL907Q50 Rear Bicycle Light. Watch videos on YouTube to understand how it works; it has an easy menu with one button.

It is a nice little light, good in the city, the plastic at the back is not stable, it breaks easily, so it needs care

I ordered four products, and one of them broke after the first charge and use. Specifically, the power button stopped working with no possibility to turn it on again.

Practical and the charging lasts a long time. With included cable. Proof that greater practicality is found in the simplest objects

I bought two and one of them burned immediately.
The other one does the job, but the battery noticeably decreases after a few charges.
I suppose it's okay if someone wants something cheap and it will serve them.
If you want durability, go elsewhere

The rubber band is a bit tight but it's convenient to have it in my saddle bag, as it fits perfectly. The quality is like a fake Sure, but it's lightweight, has 3 modes, and does the job just fine. I don't know how long it will last, but I would buy it again and recommend it!

Strong light with 2-3 light pattern alternations, the charging is fast and the light has durability! Very satisfied after 4+ months of use.

What can you say first... For 1.5 euros, there is nothing better... Battery that lasts 2 hours continuously, strong light, 5 functions and rechargeable. Highly recommended!!!

Very good. I use it on my bicycle. Just the button requires a lot of pressure to turn on. At first, I didn't realize it and I thought it wasn't working...

What can one say about these money?
The product is excellent. Lightweight, easy to put on and take off, charges very quickly, and lasts a long time (unless you ride a bike for more than two hours without a break). For its price, it is the best value for money considering that after 4 years of occasional use, and leaving it uncharged for a long time, it simply came back to life with just one charge and works perfectly again (although with reduced battery life - around an hour).

I bought 2... It looks very nice in all aspects.
It is lightweight with moderate build quality (excellent considering the price), but it does not have user instructions. It requires continuous pressing for on/off and instant pressing to change the mode.
One of the LEDs lights up while charging.
It comes with a charging cable and 2 rubber rings for thick-thin handlebars.

If it holds up, it will be great!
