I love that it keeps track of all the different items from your skin temperature to your menstrual cycle, which I no longer have your heart rate your sleep, which I don’t agree with because I know I lay awake at night and it says that I slept 98%, which is good. I tossed and turned and I know for a fact I’m awake so that’s the one thing I do have to disagree with, but other than that I do like the ring my hands swell a little bit too much so I have to switch it back-and-forth from my index finger over one and then when the swelling goes down enough if I can get it off and back on to have that snug fit. I did the sizing rings first for sure did that for two full days maybe a little bit longer just to make sure. A size 10 would work, but it just gets way way too tight on my finger.
