Smart Ring for Men/Women - Smart Ring Health Tracker - Sleep Tracker Ring, No App Subscription, Support 6-7 Days Battery Life (Size 8), Dark Gray, SR0008

Very disappointed in this product. I bought it because it had good reviews and the price was good. I'm returning it the day after I received it. The manual is useless and the app doesn't work. It wouldn't sync with my watch and I couldn't get it to pair. I tried to find information on the internet but even the brand website didn't help. Not worth the frustration in my opinion.
