I bought it to track the pulse during a workout, if the pulse reaches values above 120, then it feels like it stops reading and shows about 120, although in fact the pulse is 140-150. I checked it using Apple watch 3 (my wife's) and mechanically (on the radial artery with a second hand). If accurate heart rate values are important to you, then I do not advise you to buy. Everything else is ok.
