Easy to Use, Reads Quickly
With upper respiratory bugs going around including COVID, RSV and influenza, this is a must-have device for checking oxygen saturation levels.It’s quick and easy to use, taking maybe seven seconds for the readings to appear.With the low cost of this item, it should be as common to keep on hand as a fever thermometer is. Both items will help you decide when it’s time to seek medical advice for an illness.The back battery cover is simple to remove and fortunately takes two AAA cell batteries – not expensive button cells.Overall, it’s a great value for the price and function.

Great little device to add to home first aid kit
I purchased this at the recommendation of my wife so we could add it to our first aid kit. She is a nurse treating COVID-19 patients, so she is concerned that she could be exposed to the virus at some point. She wanted this because one of the earlier signs of being positive for COVID-19 is apparently having low SpO2 so this is simply a tool to help her check herself or me for possible early signs of the virus.She was quite happy with the little sensor, as the display auto-rotates depending on how you are holding it. This simply means you won’t be having to try and read it upside-down if you have it on one hand opposed to the other.Another thing she was quite impressed with is that the display also shows the waveform of the pulse. According to her, this is useful as it can show if it is getting a good reading or not. Because the display is so small, the waveform isn’t all that precise, but it is good enough for her to use it to improve readings.Also it is worth noting that while this obviously works on both my and my wife’s fingers, we found it also works on our children’s fingers (age 2 and 4). I have seen pulse-ox sensors specifically for children and while that might be more necessary for someone using it more often, this larger sensor works just fine for their smaller fingers, as long as they hold still and have their hand/finger resting on a table for stability. Results for them also look accurate so that was a very nice surprise.In these crazy times it seems having one of these in your first aid kit might be a good idea and the fact that they are inexpensive makes it a no-brainer.

It works well!
I bought this to check my mother’s spo2 levels quickly since she has moments where it goes down out of the blue. Its about the same size as the rest of the others out there. It reads quick, seems accurate and has a handy strap for the neck that is easy to disconnect it from if you need to grab it fast. The color is also really cute!

Works Well; shows waveform for heartbeat.
Works well. This model. even though it is is quite inexpensive, shows a waveform for the heartbeat, making it easy for me to spot atrial fibrillation (A-Fib)
