It has many adjustment options, very satisfactory, quite strong light, easy installation but it is not very stable under vibrations.

Value for money, small and with satisfactory light so that you can be seen. There are many different flashing modes. The battery lasts about 5 days and charges with USB, which is good and convenient compared to using batteries.

The light is bright and the battery lasts a long time. My only issue is with the mounting strap, it could be a bit more sturdy.

I bought it for a children's bicycle and I was very satisfied. Strong light, with different patterns, rechargeable. Very good purchase!

I have it for two days already, it looks very good, I want to see the battery life after several charges how long it will last. What bothered me a little is that the switch requires a specific press to change the brightness, etc., but for 7 euros it's worth its money and it's very bright from afar!

It does its job very well, the battery lasts for many hours and it has never run out. Also, the light is very powerful. I bought two sets, twice, as the first time they were stolen from me. I would buy it a third time as well.

Very good product with a very good price. The fact that it doesn't take batteries and charges with USB makes it very convenient. Also, the way it connects to the bicycle through its elastic strap is easy. The only negative is that you can't lock the tilt angle (it has 4 different angles), so with the movement of the bicycle, it usually takes a downward tilt.

Very good, powerful light (and adjustable mode) with a battery life that is far beyond the trip you will take.

Very convenient, very bright and rechargeable through the USB cable it contains. It has a charging indicator that turns green when fully charged. Its base has a hidden screw for the mechanism that slightly adjusts its angle, to look upwards or downwards. You may need to tighten it more because, with the vibrations of walking, the light ended up looking downwards. I tightened it and everything is fine. However, I wouldn't take it for a mountain hike. It's great for the city though!

Powerful light with 5 lighting modes.
Charging with mini-USB (cable included) at 0.5A.
Good attachment with rubber (fits most handlebars).
The battery seems to last for a long time.
Overall, a value-for-money construction.

The only negative aspect is the average design.

The bulbs are bright and it takes about two hours for the device to charge. It seems to have good build quality, but sometimes you press the button and the lights do not turn on or do not proceed to the next lighting sequence.
