    bought my ring May 28, so I’ve had it less than a year doesn’t hold a charge for more than a day anymore. Also doesn’t tell me when it’s about to die.

    The first couple of weeks the ring held its battery. Now battery only lasts about a couple of days.

    Was defective and was not allowed to exchange for the price I paid & was told to pay the difference. I’ll never buy from Best Buy again.

    Stopped picking up heart rate - Followed all their instructions to fix but nothing worked and now they say it is not their fault. Bets Buy says there is no warranty which I thought was illegal in NYS.

    the battery life was a week -- now it is less than 2-days, and it has been 7-months of ownership. I have been very careful about battery life, as I own a Tesla and understand Lithium care.

    Ring is way over priced for what it does. Bought a ring $300 cheaper that does the exact same thing with no subscriptions.

    I liked it, but my fingers swelled. I tried both sizes 8 and 9, but they still felt uncomfortable. The ring didn’t detect my sleep accurately, which was the main reason I bought it. So, I had to return it.
