I ordered from Amazon (as the leading site said, delays), and it came the next day. 2nd day wearing it, it already shows me my sleep patterns, stress levels, recovery rate, and so much more. It is brilliant for those wanting to improve their health and optimize their performance. You need to wear it for four days to gather all your data, but it already shows me so many insights. Highly recommended!

I bought this as a birthday gift for my husband. He is quite happy with the product. How good it is in terms of tracking and performance will only be known after some data is collected and compared with his other device. Hope this will help him understand his recovery patterns after long runs.

I bought the Whoop band for my 18-year-old son, who plays high-level hockey, and it has truly taken his fitness to the next level. I was skeptical at first—wondering why he didn’t just want an Apple Watch or Fitbit, which track fitness and offer other features—but after seeing the detailed analytics this band provides, I’m blown away. It’s far more advanced than anything I’ve seen with my own Apple Watch or Fitbit. One of the coolest features is that it syncs with his teammates, allowing them to compete and compare who worked the hardest during practices and games. It also tracks recovery status, which has been a game-changer—he’s getting more rest now instead of staying out late, and I love that. If you have an athlete who’s serious about their fitness and performance, I highly recommend the Whoop band. It’s not just a fitness tracker—it’s a tool for real improvement.

Great fitness tracker! Very accurate in tracking steps, heart rate, and sleep. The battery lasts long, and it’s comfortable to wear all day. Definitely a great companion for my workouts
