This device is simple and easy to use for taking you blood oxygen level and heart rate. Good value for the money!
Like the title suggests, it works, seems accurate, and is easy to use. Helpful in tracking Sp02 when I was sick.
Reasonable price and works well.
Bought this product for my moms who has COPD and she is finding it to be accurate and easy to use and read. She was also impressed as well with the EKG reading it displays
I bought this model because there’s a review from a doctor somewhere in all of the reviews. I decided to take his advice and buy this one and I’m not disappointed at all. Super easy to use the readings come up in about 15 seconds and it’s accurate. When my chest is a little heavy my O2 goes down put on days that I’m breathing well it’s up
