  • Keep up with your health
Absolutely love it!! Got this size for my thumb and it is super comfortable to sleep in for sleep review. With the app I can check my blood pressure, heart rate as well as oxygen level. Works great!

  • Just OK- you get what you pay for
Color: Rose Gold Size: 7
The fit is good and comfortable but the data does not seem correct. Steps are at least 1,000 off from my Apple Watch as is heart rate. It doesn’t pick up workouts and only notes that I wake up in the night if I get out of bed and walk around. You get what you pay for.

  • Simple and works!
Color: Black Size: 8
I like it! Price was affordable. Sizing was a challenge but Im making it work. I didn't want to commit to the endless cycle of a F.bit. been there. Done that. This is unobtrusive and provides me with insight to my 'numbers'

  • Beware of ring setup
Color: Black Size: 8
The ring works as it should. But when I set it up, I was required to enter a credit card number, it clearly said I would not be charged. Two charges appeared on my card from different places immediately for a little over thirty dollars each. I waited for them to fall off, they never did. Guess I will have to dispute the charges through my credit card company. Ridiculous. ... show more

  • Short life battery
Color: Rose Gold Size: 7
Battery dead after 3 days use. Poor quality. Can’t restart and make it work after many tries.

  • Smart ring
It run true to size, it provides me with important information: my sleep, my mood,my exercise,my breathing. It's very useful if you want to track these things. It's very comfortable, convenient and easy to use.
