My doctor told me to get a finger oxygen indicator. I’m retired on a budget and I wanted to get one asap so I picked this one. I also liked the aqua color! I got it the next day and started using it immediately. It’s fast, accurate and very easy to read. I went to my doctors office today and to my surprise they also use the exact one😂

Affordable and worked well.

Reviewed in the United States on February 17, 2024

Verified Purchase

This is going be a simple review. I purchased this for my daughter who lives in another state. She received it. She said it had no issues upon her inspecting it. Also, she said it matched the ad.

She used it on herself and compared the results to one she has at her work, since this is for personal use at home. The results between the two were not statistically different in back to
Back testing.

Overall, it’s affordable and it works well. The readings between this, and one she uses at work matched within reason. Durability, reliability, has not been established, but based on what she said and how she’s using it for personal use, it should hold up well overtime.

She said she would recommend this to others.

After I figured out how to use it correctly and understood the reading I realized it is a really good little machine. It helps me monitor Blood pressure and Oxygen levels which are two things I need to stay on top of now. I do recommend this machine it's easy to use it was just me who didn't understand it LOL. If you have any type of health issues you shoud be getting one of these to help you improve and keep track of your BP and Oxygen levels. I highly recommend these to everyone who needs them.

Works Great - But We Had a Surprise

Reviewed in the United States on April 24, 2024

Verified Purchase

Ours works great. We got it to verify a doctors office order for supplemental oxygen after surgery. We found that my wife's Raynauds Syndrome (which results in cold hands) affected the oxygen reading. At first we thought it was not working for her, and then I tried it and it worked perfectly for me. When she warmed her
hands in warm water and then tested - it worked great for her too. We subsequently spoke to the doctor about the reading and he suggested we mention Raynaud's to the medical crew when they are measuring the blood oxygen (so that they don't send oxygen home after surgery).

This is a standard, affordable pulse ox/pulse reader. It has an easy to read display and takes an accurate heart rate (I compared it to wrist and neck pulses and it was correct). I can only assume it is accurate in recording oxygen %.
