The heart rate monitor is pretty decent, I've been daily driving mine for quite a while now and am more than happy with it.

  on the whoop? my experience is it's slow to pickup changes & consistently 5-10 bps lower than other bands / pulse ox. But my biggest gripes are the auto-sleep detection is horrible for me, and my sport isn't really conducive to the whole value add of measuring 'strain' in the way they do. Doesn't really catch short but very high intensity bouts of work. So like if I can't get good sleep recommendations or measure my strain/recovery I don't want to pay $30 a month just to see a heart rate pulse on my phone when working out. It hasn't improved my training in a meaningful way.
