dying battery render the ring useless, free replacement seamlessly provided
Product works as expected and is hepful.After 7 months of usage battery is dying, resisiting less than one day after full charged. I contacted the seller, and free replacement arrived in couple of days, no need to return the mafunctioning one. As such, a one star reviewe turned into a 5 stars.

Life changing if you’re willing to put the work in
I’ve had it for a month now and I can say it really keeps me on track not necessarily health and fitness but more habits and trends. I think everyone can benefit from it. It came neatly packaged and sealed 100% new and after wearing every day I definitely have a lot of small scratches (and I take it off for showering doing dishes etc) but not visible to the normal eye

Tracks almost correct - sleep tracking needs improvement though
Tracks almost correct - sleep tracking needs improvement though - I wake up many times and it does not track that so well
