WHOOP 4.0 (with 12-Month Subscription) – Wearable Health, Fitness, and Activity Tracker – Continuous Monitoring, Performance Optimization, Heart Rate Tracking – Improve Sleep, Stress, Recovery, and

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.

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

The device log out be its self specially when i sleep ( just less than a month from the purchase), i try to contact the seller but there is no respond, not recommended at all
