Medical analysis ring.
Works well. As far as I e noticed it functions as well as the mega priced rings and provides the same body functions as the over pro rings.

Highly inaccurate bpm and bp - Do not use.
Highly inaccurate bpm and bp - Do not use. Consistently off by 30 to 40 % do not use - too inaccurate. Base lined with traditional stethoscope and BP CUFF and consistently inaccurate. UNDER counts BP. BPM is off by 10-15% . Would not recommend purchasing or owning. False sense of accuracy.

Kinda crappy but ok
Well, it works, pretty much. It loses Bluetooth connection, you have to rebind it to the phone repeatedly, it just stops working randomly, and over the last couple weeks that I've had it, it's gone from needed charging once a week to every 2 to 3 days. But when it works, it works, for pulse, O2, and blood pressure. Sleep doesn't work very well.
