Blood Oxygen Saturation Monitor, Pulse Oximeter Fingertip, OLED Portable Oxygen Monitor, O2 Saturation Monitor, Heart Rate Monitor, SpO2 Finger Pulse Oximeter with CarryingCase,Lanyard,Batteries,Black

One of the strange symptoms of COVID is a dramatically lowered blood oxygen level that is dangerous but apparently the patients isn't even aware. This little device does a great job of checking your pulse oxygen. The same device can be used by the whole family. It just takes a few seconds -- and is nice to read a pulse Ox of 97, 98 or 99. Good value and good addition to my medical supplies.

Works as advertised and is very easy to use. It even came with batteries. Was very adorable.

Really like quality and accuracy

This was to replace one we had purchased during the pandemic, this one comes with the batteries so you can use it immediately. It has a small case & lanyard

Comes in handy when you are a CNA & nun of your work equipment is working. Works perfectly.

I checked the heart rate along with my Apple Watch 4, and that was within 1-2 bpm. When my heart rate is 80 on the Apple Watch, it's 79 on this gadget, and when it's 65 on the Apple Watch, it's 64 on this. So I think at least the hear rate measurement is pretty spot on.I'm not sure if the spO2 is perfect, but just looking at the construction of this thing, and the way that the display has a little graph of your heart rate in real time, I can tell that they really put some effort and thought into this, so I'm learning towards this product being pretty good in terms of accuracy in spO2 also. Anyway it has CE European certification, which I think is as good if not better than even FDA certification, so I don't think accuracy will really be a problem with this.In general this things is pretty high quality at a decent price.

Family members all have one of these and we all bought different units. I like mine the best. Fastest reading, large, clear readout, and the heart graph trace is the most detailed of all of them (2 don't have the graphic trace and only report Beats/Min). My brother has an irregular heart murmur and it shows up on my graph (pretty neat, really).Not sure how long the batteries last, but it has been in use a few months and I use it every morning and it is still going strong. No complaints at all.

I love this product is easy For me to check my CO2 levels in my blood and after getting out of the hospital I still want to monitor that so overall it’s well worth the price and it’s a great product if you’re looking at managing your personal healthcare better
