Excellent

unusable for my electric bike

I had high expectations for this thing. They were not met, unfortunately. Works, but not really more precisely than just using your eyesight, not precise enough. Maybe with a metal casing that would snap into place very precisely, much more tightly than this does, who knows. I quite liked the idea, not so much the execution.

It doesn't work. It won't turn on after a full charge. It seems to be broken.

It works well, delivery was fast, and I am satisfied.

Arrived very quickly. Works very well and is easy to set up. good strong beam for alignment. Charges via USB so no need for batteries. just about clamps onto my mountain bike bars. you might struggle if your bars are very thick
