12%of 32 owners recommend

Owners praise

Bicep band disappears during sports like BJJ, hockey, and basketball once sized correctly, staying put without bunching or distracting the wearer

Owners complain about

Owners upgrading from the 4.0 feel let down by the subscription model, unable to carry over old bands, facing renewal/upgrade fees, and several have cancelled outright calling it extractive or a scam
Heart rate accuracy during exercise is significantly off versus Garmin, Apple Watch, Polar, and the Fitbit F8 -- readings run 20-30+ BPM low during strength training and spike erratically (180+ BPM) from arm vibration while cycling
Calorie burn and step counts read far lower than Garmin, Strava, and Oura for the same activity -- some owners report Whoop crediting roughly a third of the calories other trackers show
