great for the value

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.

Good product...but horrible on the delivery time considering the facility is 20 minutes away.

Too thick and bother when wearing it.

Love this ring. It’s works as good as those more expensive rings.

I thought I would try the cheap model and see how it compares to the other one that was $250. It’s junk. Didn’t monitor my sleep correctly. Not close.

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.

Runs large but works well
