I also have this watch. Have had it maybe two weeks It’s ok.
I wouldn’t pay the $300 retail for it. Got it for $120 on amazon. For that price, it’s alright. I was looking for a whoop alternative and the advertising/marketing for it seemed like a solid choice.
The stress score is low and I need a bit more time for it to be a bit more accurate. The sleep tracking is pretty nice and I feel accurate. I too like this as a watch and having smart notifications is a nice addition as I hate having my phone with me/checking it all the time.
Then again like someone here said: do you really need a device to let you know when you’re tired or peaking? We all know when we have a lot of training load/stress. You feel it.
