when it stays on it's great

Overall it's a very good tracker. My only issue is sometimes it appears to turn itself off during the night and you get no sleep data. When it does stay on the info is very good.

Expected Better Sleep Results
on August 11, 2025
Posted by: Wicker53
I received the Small/Medium band two weeks ago. I don’t like sleeping with a watch, but wanted integrated sleep/recovery/HRV results. I was hoping that this would replace the Oura ring that I’ve worn for 5 years. However, I found the results to be very inaccurate against the Oura ring, which I’ve come to find as reliable and accurate (and as corroborated by testers) as are available outside a sleep laboratory. I’m hopeful that it will improve as it adapts over time but am disappointed against hopes and glimpses I’ve seen from napping while wearing the Forerunner 945 and 965 the past few years.

Finally I can track my sleep
on August 11, 2025
Posted by: Pigeonmachine
I made the decision, long before fitness watches with heart rate tracking came about, to get tattoos on my forearms. And so I struggle with HR monitoring -- wearing a chest monitor when I run. Sleeping in a watch is impossible. Inevitably, the tattoos get in the way. The new sleep monitor, which I wear on my untattooed upper arm, solves this for me. Super comfortable. Really works well -- it definitely seems much more accurate than the very erratic wrist measurements.

Seemed like a good idea…

The band is somewhat uncomfortable where the two ends wrap through a plastic loop. It needs a flap like the chest strap has. Also the syncing is a mystery and I no longer receive my daily summary that I used to get on my Fenix Pro

Very comfortable to wear.

I use it when I sleep so that I can remove my Garmin watch. I believe it is a little more accurate. Also give my rist time to relax during the night. I would recomend this mainley for the comfort and ease of wearing.

Comfortable- Doesn't always register wake ups
on August 11, 2025
Posted by: Chris1123
I have been wearing this for a few weeks and I like it. First the cuff is comfortable. The battery lasts several nights between charges so happy there. A few times I have woken at night and I am not sure the cuff registers it, but these are usually brief so it might just record it as restless. The data differs from the Fenix 8 I was using for sleep tracking, with the Index cuff recording a higher sleep score.
