    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!!!
