Ultrahuman Air älyrengas

Yeah works fine, I wake up in the morning and think I slept poorly, and the ring tells me “you slept poorly”… great. Bit of a waste of money but it works

The ring never connected, support from ultra human is terrible. Don’t waste your money

Great product to determine the correct size of ring required

This has been such an amazing purchase. Almost two months in and I love it!

yes , it is excellent when you are looking for your ring size
