So far I LOVE it. Should have bought it last year instead of fighting with a body band.

Accuracy seems good. I was able to map it to my Kinetic Inride app right away.
I don't use the beeping as I read straight from the app.
Recharged it once so far and batterie is still showing full after about 3hrs of training.

One of my best sport purchases (beside my Amira bike) ever!
