Works great with 5 day battery before needing a charge.

It’s comfortable, looks very nice and tracks my steps, oxygen level, pulse, sleep patterns , and temperature. Even can take my blood pressure pressure, but it appears to show a lower blood pressure than my arm cuff. It’s still nice to track it though with the ring. I first ordered the ring sizing kit and that helped me buy the perfect size. All I all I like it very much and it is reasonably priced. It is dust proof and water proof, but I’m not pus that just in case and have been taking it off before showers bu leave it on when way my hands. The battery lasts me 5 days before needing a charge and I’ve only had to charge the battery case once. Read more

Instructions are absolutely useless

Tried two watches. Neither ring would work would not connect. Instructions are very vague and generic. Don’t even match this ring. Had a techie friend try and he could not make it connect either it simply a defective product. Read more

Works Fine After Charging, Decent App Connection

Smart Ring for Women Men, Fitness Tracker with Health Metrics Tracking, 20 Sports Modes, IP68 Waterproof Titanium, 7-Day Battery (Silver,8#) The ring arrived with the battery completely drained, so it needed a good charge before I could test anything. After that, it connected reliably to the app on my phone and the charging case worked as expected. Fit-wise, it was close but not quite comfortable for long wear. The material felt like it might bother my skin if I kept it on all day, so something to keep in mind if you’re sensitive to certain metals or finishes. Functionally, the tracking features seem solid so far, and once powered up the device behaves the way it’s supposed to. Just a bit of a rocky start with the battery and fit. Read more

Crap

I will never buy another one finally got it to charge only for it to go dead two hours later. I bought it for my daughter so we can keep an eye on her heart rate but it’s not worth it if we have to keep charging it. Read more

Excellent

I cannot believe how good this is for the price! I've only had it for 2 days but linked to my phone it gives me everything I need at a glance. Tracks my sleep, BP, heart rate,pulse during my activities all day. Why would you spend $300-$400+ on a ring when this does it all? Read more

The battery doesn’t last that long even with 2 hour charge. The size fits great, feels comfortable and looks great. Read more
