To be utterly sincere, I wouldn’t usually use the T-Rex 3 for sleep monitoring—carrying a 48.5 mm gadget in your wrist in a single day isn’t precisely snug. However for the sake of this evaluation, I gave it a attempt. For those who do resolve to put on it whereas sleeping, the outcomes are first rate, intently matching these from the Amazfit Steadiness, which is the corporate’s greatest gadget so far for sleep metrics.
