chris snyder –
Amazing ring! It has tracked my every step, my sleep, and my heart rate and o2. It’s so good for the price!
The battery lasts for at least a couple days I haven’t tested past that yet! It’s great! I got a size 9 and can wear it on my index or middle finger.

Works great!

This is a pretty sweet ring. I always wear an Apple Watch, but this is really nice because they wear it to sleep at night. I hate wearing my watches asleep at night. This will monitor my sleep without having to wear my watch. I really like this.

Received this smart ring a few days ago and I am obsessed! I love how it tracks my health stats just like the big name brand smart rings, but for a fraction of the price! It is sleek and looks very high end. I ordered a size 7 and it’s true to size and fits perfectly! 10/10!!

I’m very new to this ring and it tracking everything but it seems really cool and i’m glad i’m trying it out! it came just as described, charging case, the ring , a ring sizer, the charger , directions , and it came with a rubber band to go on the ring not to sure what it is but I love everything. I haven’t connected to the app yet because it’s charging, but the app works pretty good. I made an account. The sellers were very nice and helpful and I would purchase again. 10/10!! 😁
