1100 Bike Light Cut-off Line Beam Bicycle Light For Road MTB Bicycle Nighttime Cycling 1200 Lumens 4000mAh

The light looked very promising. I mounted in on my CAAD12. After charging it, I shined it at my backyard. The range seemed bright, long, and wide. Even the low beam seemed like enough. Yesterday it was very difficult to turn the light on during my group ride. I couldn’t turn it on wirelessly no matter how much I tried. I had to stop to turn the light on manually. From the very beginning, it seemed very difficult to turn the light on. I had to press hard and long. I don’t expect much.

the light is ok, high and low beam function. I used the mouth they provide and now it's stuck in it, I cannot remove the adapter now. no matter how I twist and turn.

Both the product description and the 'user manual' are incomplete. The light also has some issue with functionality. It will randomly switch to a predefined mode/s and if you want to go back to your mode (e.g. flashing, medium beam, high beam etc.) it either won't do it or switch back to this other mode immediately. It is not from low battery or overheating. Unfortunately the seller doesn't stipulate a return period and are not interested in helping.

we have to test for durability; initial quality is perfect

This flashlight illuminates well, but the battery lasts very little in the Maximum mode, not even for 2 hours. After that, the flashlight itself reduces the light intensity to the lowest level. Another bad point is the charging time, which takes a long time. The remote control works normally and responds to commands.

Very bright and solid made
