Ultrahuman Smart Ring AIR

I’ve owned the ring for three weeks, for the first two weeks the ring was good, lasted approx 4/5 days between charging, now I can’t make it through the day or night. Charged before bed and it was flat by morning. I have contacted Crooze to return the ring as it’s useless if it can’t make it through the evening since I purchased it for sleep tracking. I’m really disappointed in this product.

Still learning about the all functions.

Loved that you can get a sizing kit set out before locking in tour ring size however, I think the sizing rings run the tiniest bir smaller than rhe actual ring. I ended up going with a 6 (after trialing the sizing ring) as it fit my finger comfortably, however the actual ring (size 6) actually slides up & down my finger a bit. Other than that, have been loving the ring. Extra points for Crooze for their great customer service and fast shipping.
