FL400 Pulse Oximeter with Neck/wrist Cord, Carrying Case and Batteries- White

Absolutely accurate, long lasting, dirt cheap. This is my second one. The first one still works, but got so old that I replaced it

I bought this during the pandemic to monitor my elderly parents’ blood oxygen levels. I also kept tabs on my kids and myself. It was easy to use and seems to work great. I am assuming the readings we get are accurate since we seem to have varying blood ox levels. I will say this product was recommended to me by a nurse and she has had hers only 1 week longer than me and hers broke already. (Her company won’t replace the one she uses for work.) Hers gets more use but you would still expect it to last longer.

We got this oximeter so that we could monitor oxygen levels in case one of us got sick during the pandemic. We figured it would better help us know when difficulty breathing or shortness of breath warranted an emergency visit. While we are thankful we haven't yet had to use it for that exact purpose, I did become ill with a mystery sickness that ended up being a really bad strep infection (throat, sinuses, and ears), but I was able to rest easy knowing my O2 levels were good the whole time. It was also interesting to monitor my heart rate, which was markedly elevated during the worst parts of my illness, and returned to normal as I started feeling better. I love the peace of mind of having this on hand for future sicknesses to better monitor myself, husband, or kids. It is very easy to use, gives a reading quickly, and is something even my children don't mind having used on them. Plus it's very small so it stores out of the way when you don't need it.

Works well most of the time. I tested it against a medical-grade pulse monitor. They agree most of the time, but if you don't have it seated well on your finger - it will miss beats and read low,

Quick accurate results. Results were comparable to top name brand used at the hospital.

Just as I expected, easy to use and accurate. Only thing is that first time I used it it took a few seconds longer than expected to catch my reading but that could be because it had just come out of the box.

Works great. I have a heart condition and I needed a portable heart monitor to carry with me in my purse. The size is great and lightweight. I have had this product for around a year and i have not had to replace the battery yet. It has a very clear and easy to read display. Shipped quickly.

I have a small hand, so I had to use my thumb for the readings
