I bought one. Returned it the next day. Utterly useless if you already have a smartwatch. It only measured my pulse once per hour and it cannot measure SpO2 except when you're asleep. My watch measures my heart rate continuously and it can manually do an SpO2 check any time.

And they look like a toy from a box of Cracker Jack. Seriously. I know they're made of titanium and they're very expensive, but they looked and felt like cheap metal-painted plastic.

You're supposed to wear it on your index finger, not your ring finger, which is really weird if you're used to wearing rings.
