  • 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. ... show more

  • Oxígen
This pulse oximeter is easy to use and gives quick readings. The display is clear and easy to read, and the compact size makes it convenient to keep at home or take with you. It’s simple to operate and works well for checking oxygen saturation and pulse rate.

  • Ok but..
If you're getting one of these for yourself you can't just hold your finger up and read it you have to turn your finger the other way and if you can't do that by the time you take it off the screen goes away.

  • Excellent product

  • Accurate and Affordable
I've had this pulse oximeter for a few years now and it still works. I've been using it at work and sometimes it takes a while to get a reading, but the readings are pretty accurate. I like that it comes with a lanyard with a lil clip to detach it. It's not a bad size, would've been nice to have a few more color options, but it works for what I need it for and was very affordable. I ordered a more expensive one because I thought a different color would be cute but honestly this one is better I'll be returning the other one. 😅 ... show more
