I got sick recently, and one of these was really helpful
I had one for my mother when she needed it. I kept it. Now it’s my turn. I need a couple of times to check my health. It caught me having a sleep, problem, which I didn’t know about. I checked it against my Fitbit watch and also I was in the hospital and compared the readings as I brought up with me. I’m not a scientist, but I can tell you that the readings I saw were almost identical enough for me to buy this unit, which is the updated version of the one I have and that just compared them against each other and they totally agreed. The safety something like this can give you especially with external replacement batteries so you don’t have to wait for something to charge up or something that’s no longer charges up. This is the perfect answer. At this price you’re gonna afford to buy a few of them and leave them at different ends of your house or different rooms or one at work one in the car in case you need to know. You can’t beat this kind of piece of mind at this price point.

It works providing heart rate and oxygenated blood levels.
Does what expected of it - but I don't really know how accurate it is. A useful guide!
