    Great idea, fit snug, feels solid. They need to make the app free and offer lifetime firmware upgrades.

    I ordered the wrong size on my first one, the sizing is a little different than actual ring but once I got it I loved it!!! I wonder how long it will function but I have had it almost two months and I love it… I use it in cold plunges, hikes cooking cleaning etc and it lasts great!! I don’t use lotion or anything in my hands I take off if I use hand sanitizer but it is worth the effort for the information it gives you about what your body is doing!!!

    This is my first Aura ring. I’ve been wearing it for about 3 weeks now and so far I have been very happy with the accuracy of it and the information it provides me on what stressors my body is under. The only reason I gave it a 4 instead of a 5 is because it scratches so easily. I spent extra to get rose gold since it’s something I would be wearing all the time. It’s a beautiful ring but I’m not sure in a year what it will look like if it’s this scratched in just 3 weeks.
