I was skeptical, but this really works. I am very impressed.

Easy to set up and the app makes it so easy to monitor your vitals.

Nice ring. Hopefully, it will hold up and does as specified.

This ring is pretty cool. It does several things like blood sugar, blood O2, heart rate and it looks like fairly accurate readings. Easy to install and it doesnt die battery wise that fast.

I'm pleased! It works great! Excellent price! Excellent quality!
