This is a great product. The only downside is that the instructions are only in English and Chinese, but apart from that, it's very good.

This is a great product, and it arrived quickly. I plan to order more in the future.

This is a great product and it functions as expected. The only issue is that the caution sensor is difficult to attach to the very thick fork. Because of this, it's not appropriate for my Orbéa bike, which, in my opinion, is a real road bike. It's unfortunate. I think it would be better suited for an ATV.

The Polish Lamp arrived quickly, within 10 days, and includes a built-in wire connection meter, handlebar mount, and outputs 350 LM of brightness. It charges via USB with a 1200 mAh battery and features extra buttons for light and sound signal, along with a steering wheel mount for convenient placement. The lamp provides clear and perfect illumination for the track, offering 5 light modes. A built-in backlit counter displays the relevant information. Everything matches the product description. I recommend the seller and the product.
