    I’ve been using this for about a month. It does a great job giving me an idea of how my sleep has been and if I have any breathing irregularities. My main issue is that you can’t edit an activity from a previous day. It does a good job of recognizing when you are working out but sometimes it gets the length of the workout wrong. If you don’t edit it that day then you can’t the following day. Others have complained about this as well. Hopefully a software update will fix this oversight at some point.

    I've owned this for a little over a month now. Fantastic tracking overall. I've not noticed any inconsistencies with it yet. However, you MUST take it off if you work with electric impact wrenches or you may damage the sensors. Other than that, great product!

    What a great device! It gives me more insights than I expected. I like that it tells me that I need to relax, or that I am "coming down with something" before I even feel any symptoms.

    I got this about a month ago and I’m liking it, good info on sleep and stress patterns. Charging every Sunday so far, takes about 45 minutes to 1 hrs to charge depending on the charging block you use.

    I'm tatted, a lot. My expensive Garmin fenix 7 doesn't track my health anymore - but it's a great watch. So I decided to try a ring so I can get my workout and heartbeat stats. Initially I tried the Samsung ring, since it didn't have a monthly subscription. Didn't like the design of the ring and heartrate was only on demand. Meaning I had to go into the app and tell it to check HR. Oura is much better, with way better insights on HR and sleep. Syncs well to MyFitnessPal.
