Love it. I don't like chest straps, and as an avid road cyclist, my Apple Watch doesn't really sync with Garmin Connect, Strava, or other popular apps. hours between charges. I can't say how long it takes in practice. I ride about 2 1/2 hours straight and if I don't charge it for 4 rides it still works. Some have complained about the strap. So far I've driven 1000 km, no problems. Accuracy is excellent and matches my Apple Watch reports well.
