Finger Pulse Oximeter with OLED Display - Blood Oxygen Saturation & Heart Rate Monitor for Adults & Children

It arrived a day early which was nice. Fits the finger snugly, came with its own batteries. However, it did not work. I followed instructions inside and called the supplier, he was happy to replace. Replacement arrived in 4 days and came with a thank you gift.Unfortunately it doesn't work either. I would NOT recommend. Edit 05/21/2021 I gave this a harsh review at first. The seller made good on his promise to refund money and went out of his way to make sure we had a working unit. Seller is great to work with and I would recommend this to others. Only thing is the battery insertion directions. It is not clear and if inserted as diagram it won't work. In the end I DIDN'T pay for anything.

it didn't work and couldn't be returned but there was a note on the little box that said to email address and problem and they would replace it. THAT WORKED GREAT. The vendor sent me another one and tracking number within 20 minutes. Fantastic service.

I got this item to use because my grandson had respiratory problems and wanted to have a monitor to check his oxygen when he was struggling. Needless to say it does not register properly. After taking an ambulance ride because we were so concerned of how low this device was registering, we came to find out that it is not accurate whatsoever. It was stating that his oxygen was at 87- 88% and at the hospital it was 97–98%.This was the reading on my finger, I have no respiratory issues whatsoever. This thing is a joke!

I have had the pulse ox now for more than 3mo. I use it for work as an RT. Compared to the facilities pulse ox it is only a few points below for the HR and SpO2 levels. It does pick up artifact fairly easy but that’s expected since it is so light and small. I love that it is lightweight and easily fits in my pockets. Another thing I love is that it is quick and easy to use. It comes with a necktie and case but I don’t use them. Overall, I would definitely purchase again! This is an honest review and I was not paid.

Super simple and easy to use & super affordable compared to other brands or anything in the store. Can throw it in my gym bag and it hangs in there so it’s pretty durable which makes it easier to carry around without worrying over it. Extremely helpful for calming nerves and bringing heart and breathing rate back to normal as it makes me just sit and breath calmly and slowly while it returns to normal. Exactly what I needed and very reliable

With a worsening case of COPD, a previous major heart attack, and a double bypass, I wanted to keep track of my oxygen percentage. This Chooseen Pulse Oximeter was inexpensive, but not cheap. When I first got it, I checked it against the reading in my Doctor's office and it gave me the same percentage.It now is an at-home warning system for when I should use my Albuterol inhaler, or if I then head to the ER if my lungs do not respond. At $8.99, it is a great investment in keeping me healthy.On a comic note, when I first started using it, I put it on my right index finger. I started to complain to my daughter that it was difficult to read upside down. I then had the "Aha" moment and put it on my left hand and I can read it perfectly.

The unit works, err provides a reading, however it's cheap in price as well as in quality control and design. Cheap because it doesn't come with a case but it fit into the cloth case from my old oximeter that still works but has a plastic case that got broken during travel. Cheap in design because the batteries had to be installed according to the barely legible diagram inside the battery compartment, not according to how someone looking at the contacts would intuitively install them. Cheap in quality control because it came with a .3 cm lanyard cord that could not fit through the .1 cm hole on the oximeter I received, a hole that was smaller than the hole on all the videos people provided to show how to insert the lanyard, so I easily installed the lanyard from my broken oximeter. User manual should explain how to install the lanyard or at least point out the lanyard holes on the diagram for those who can't figure out what those two holes of unequal size are for. I get readings on this oximeter that differ from my old oximeter by more than 4%, sometimes higher, sometimes lower, don't know which one is correct so I just go by how I feel.
