Fingertip Pulse Oximeter, Blood Oxygen Saturation Monitor (SpO2) with Pulse Rate Measurements and Pulse Bar Graph, Portable Digital Reading LED Display, Batteries and Carry Case Included

Arrived fast, works great, easy to use.

It works like it should.

Update: The company reached out on their own to offer a refund and I thought that was really nice. Most places are on out to collect and not to actually provide what they sold. So its still worth giving a try and maybe it works out for you. I update one star because I thought the customer service was good. Theres never been an issue when using one of these in a Drs office, but this one seems to have quite a few issues on my finger. I have to rearrange it a few times as if it cant read my finger at a certain point. I dont know why that happens, but its important I record spikes in my heart rate and its frustrating that it can take so much effort for this to accurately produce a number for me. Its simple, open it and slide it on your finger, right? So why is it giving me such a hard time? Im not sure yet if Ill keep it. Seems many are happy with it, maybe Im a ghost...

Product is good but after 75 days or so it only lights up but it will not give you a readout of oxygen saturation or heart beat count. I do not know if this is normal but order two if you really need to monitor your oxygen levels.

Just as described. Easy to use. I order 2. One for my Dad and one for myself.

I just received this but its simple to use and appears to be accurate

This is good to have around the house. Especially as you get older. Measures your O2 and pulse. Always good to know!

I have COVID twice and was able to use this to keep track of my blood oxygen level. The screen is super easy to read and it has always been accurate compared to my apple watch. I think for the price you cant really beat it!

Easy to use.
