Very comfortable. Worth it. I forget it is on. Very comfortable to sleep with. I don't want to sleep with my watch. Very acurate data and instantly uploads when I get up and take it off.
From a sleep nerd. First, I'm a sleep nerd. At least my wife calls me that. I wear a lot of sleep trackers to bed, including the Wellue 02 ring, Oura, and Whoop. Now I've added this to my repertoire, although it's overkill.What it's accurate on: HRV, and SP02 (although it only monitors your oxygen levels every minute - which is significantly better than only Oura, which does a snapshot like every 15 minutes and therefore will miss any potential breathing events.Also - I find the breathing variations to be accurate and in-line with my Wellue 02 ring.Comfort - a major plus, especially on nights I forget to wear my 02 ring. It will let me know with very good accuracy on nights that I have some breathing disturbances and signs of mild sleep apnea (which, are usually nights I drink alcohol).Last positive: battery life is truly 6-7 days.Now for the negatives: Sleep stages I would not rely on. It does ok with deep sleep but overestimates in most situations. I am also wearing an Oura and Whoop and they both are usually in sync and this is not in sync most of the time with those two - which in my opinion are probably the ones to go off of (but I am asleep so therefore it's truly hard to say).Also - syncing is a major issue. In fact, there are nights it simply doesn't even record my sleep. Or if it does, it ends up showing up much later in the day. This continues to be an issue about once per week.I do not wear a Garmin watch. The app is still useful. I wear the Apple but take it off at night in favor of the Whoop. For most people, this will be a more than suitable sleep tracker and will give you reliable HRV, and more importantly, give you insights into potential breathing disturbances you may be unaware that you have. For me, this is a secondary device that ends up as a 4th tracker at night, and the majority of people use one / two trackers at the very most, not four like me. That's why I'm the sleep nerd 🙂
Like It. Works great as advertised. Prefer this to my Enduro for sleeping! Not a fan of wearing a watch while sleeping!This band is very comfortable. Don’t even notice it while sleeping.Works for me.4 stars because I think it’s a little too expensive.
