The lighting is good, even in daylight, and the modes function properly. The battery's lifespan is satisfactory. However, the brake detector is excessively sensitive, activating at the slightest movement, which is unfortunate.

The item functions effectively, however, it doesn't emit a significant amount of light. It's not particularly bright.

The backlight performs excellently. While the functions could be more straightforward, especially with the auto mode indicator light being difficult to see, a workaround was found. The light functions well during braking, and the blink modes are good, though a speed between the existing slow and fast options would be preferable. Overall, it's a fantastic product with quick charging, a seemingly long-lasting battery, and helpful mounting options. The packaging and shipping were also positive, so I recommend it.

Received well, very quickly. Now I just need to try it out on the bike.
