500E-B Bluetooth Pulse Oximeter

Very easy to use and accurate. Nice case to store device

Reads and gives results more quickly than previous models in side-by-side comparisons, especially when the ambient temperature is below 60 degrees (F). The app interface is helpful for tracking and comparing readings.

This unit is extremely well-built, comes with a case and protective cover, and lanyard. It synced instantly with my iPhone, so that bit integrates smoothly with Apple Health. There is no indication in the instructions about where to download the App that is required for phone integration. Once found, and opened, the results are immediately recognized by Apple Health. My doctor recommended that I have one. This is perfect for my needs and setup was fast and smooth.

I like this blood oxygen monitor. However, I could not get the wireless data recording to work. So I have to manually enter the data. That big of a problem .

Works great and I really enjoy the app. feature. You can easily record and save every.

Arrived on time in perfect condition. Had excellent feedback comments. I was a little wary as it was under $12. bucks to my door. I recently took this to my pulmonary walking test and compared numbers to the hospital's state of the art device. The pulse was the same throughout the walking test. The saturation number was low, BUT consistently by 3 points...so now I know accurately what my oxygen saturation is simply by adding 3 points. If you need such a "tool", get this one. Come with a protective woven nylon case so it's safe to throw in my backpack. buy without hesitation.

Lots of features, great display.

I was really looking forward to using the app with this oximeter. Don't waste your time. The app cant even be downloaded. So much for that. Buy from someone else. It not even worth it for the money.

I was very pleased with the overall quality of the meter. It is well made, comes with a rubber cover for protection fro the elements and a very sturdy velcro closing nylon carry case. Also supplied is an easily fitted, strong lanyard. The instructions are easy to follow and simple, yet go further to in depth explanation of how the device functions and operates. The cradle for the finger is comfortable and I had no trouble getting a reading. It is accurate alongside other meters and very easy to read. It requires 2 AAA batteries, which were supplied in a sealed package. There are multiple read formats to suit most. The price is very reasonable and delivery was sooner than stated. It was packaged well and arrived in excellent condition. I would recommend this little unit to anyone who might have need for one. I am now more confident that I can assess my heart rate and blood oxygen saturation on a very regular basis.

Uso médico hasta el momento excelente

Works well, readings are accurate and battery seems to last a long time when the device is being stored between uses. Storage case is very sturdy. No complaints.

This is my second oximeter and appears to be accurate. Heart rate matches the reading on my blood pressure monitor.

This was purchased to double check my overnight readings using my Fitbit Versa 3.This is more accurate,and more specifically designed for SpO2 readings and at anytime of day. Highly recommend,as a very accurate SpO2 readings at anytime.COVID times and non Covid times.
