Accurate, easy to read, works phenomenally well
This was easy to use, and very accurate when comparing to my Drs pulse oximeter. You do NEED warm hands or the pulse oxygen will be off, but this is standard with these devices. It comes with a carrying case and batteries! Excellent value and functionality.

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.

Very accurate and easy to use.
I compared it to my doctor’s pulse oximeter and it was very accurate. I love that it actually shows your heartbeat line instead of just the beats per minute. The screen turns depending on the angle of your hand, so no matter which way it is, you can read it. The screen is a good size to be able to see all the information easily. It is comfortable to wear.

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!

Good item and cost effective
This is a great thing to have at home or the office, especially if you’re worried about oxygen saturation when you’re sick (or not). It also shows your pulse pretty accurately. Great item for the cost.

Sirve muy bien, muy económico, con el tiempo y uso constante se debilita el resorte, pero nada que no se pueda solucionar
