Bought this item because I’ve been having problems with my heart rate every day I’ve been using a blood pressure cuff, but this finger clip is fantastic. Gives me my oxygen and heart rate.

Fast & Accurate Readings: Delivers blood oxygen saturation and pulse rate numbers in about 10 seconds with solid, consistent accuracy.
Wendy BVerified buyer

These oximeters are every bit as good as the ones that the doctor's office uses. They seem to be accurate as can be. The only drawback that I can see is that if your hands are cold, it takes a while longer to register.

When to use it
Curious how your pulse looks after a run, a ride or a gym session? Clip on and check in seconds.
Small enough for a carry-on or a day pack, so it comes along without taking up room.
Keep it in a drawer for whenever you want a quick look at your numbers.
One button and big, clear numbers make it simple for parents and grandparents to use too.
Everything you need to know before you buy.
Three readings: an estimate of your blood oxygen saturation (SpO₂) as a percentage, your pulse rate (PR) in beats per minute, and your perfusion index (PI), an indicator of the relative strength of the pulse signal at your fingertip.
No. Nimbray is a pulse oximeter. It does not measure blood glucose or blood sugar.
No. Nimbray uses light-based pulse oximetry, so there's no finger prick and no blood sample.
Sit still, rest your hand at heart level and keep it still until the numbers settle. Use a warm hand, put your finger all the way in, and remove nail polish or artificial nails from that finger.
PI is an indicator of the relative strength of the pulse signal the device detects at your fingertip. It's a signal-strength guide, not a diagnosis of blood flow problems.
Nimbray is sold as a general wellness device. It isn't intended to diagnose, treat or prevent any condition, and it doesn't replace advice from a doctor. If you feel unwell or are worried about your readings, contact a doctor. In an emergency, call 911.

I got one for my dad. He likes that he can just put it on his finger and see the numbers.

The screen is actually pretty easy to read, even without my glasses on
