AVOID THE CRAP OUT OF THIS!!! Didn’t work worth a damn in the first place so I barely tested it. Maybe a month later I got a bike and thought it’d be awesome but pulled it back out of the box and the buttons wouldn’t work AT ALL. I took it apart and was clicking the button directly on the pcb inside the casing and it just died without any wear and tear. I’d say you get what you pay for but I never got to actually use it.
