The lamp was promptly delivered. But after unpacking I could find:
1. The lamp itself makes a reasonably good impression (clear plexiglass, good reflector, massive seal, etc.), the brightness is good for the money spent, but a screwdriver can be used for battery replacement mechanism, unfortunately a charging socket is missing. This is unnecessarily cumbersome.
2. The switch is stiff and shaky, the life questionable.
3, the plug holder is a disaster. It is a very cheap manufactured plastic part that has already been damaged when first made to tighten. The screw thread (plastic !!) is rapidly round, the ball clamp immediately got a crack. I have the part thrown directly in the garbage can and a metal clamp modifizert own, so that the lamp can be securely attached to the wheel.
Unfortunately, I can thus be no buy recommendation. Again:
Who buys cheap, buys twice.
