Wellue Fingertip Pulse Oximeter, Blood Oxygen Saturation Monitor with Batteries & Lanyard for Wellness Use Bluetooth, Black

Works well and app is easy to use

I recently had aortic heart valve replacement. This is an absolutely fantastic pulse oximeter. The app is great. I can send screenshots to my cardiology team.

I purchased this item because I had previously purchased another product from the same vendor (Wellue): the O2Ring Wearable Sleep Monitor, with which I am very satisfied (I wear it every night to alert me should my O2 level fall below a set value). So I had high expectations for this pulse oximeter, given how well that "O2Ring" and smartphone app worked together. Unfortunately, not all my expectations were met (but that is understandable, as I will explain). This pulse oximeter has just basic functionality in that, unlike the O2Ring, it does not [as I expected] have any recording capability. In other to examine its meaurements, the smartphone app has to be running; that I did not expect. The combination of the two (this pulse oximeter and its smartphone app, working together at the same time) can record its measurements, but not if the app is not running. Their O2Ring, in contrast, records its measurements within itself (so you don't have to have their app running on your smartphone at the same time); the stored data are available for download afterwards. That's fine, given that the "O2Ring" costs five times as much as this unit. Given the low price, I understand why there is no on-device data recording capability. Its function is, simply, basic. That said, what about the accuracy and responsiveness of this pulse oximeter? It appears to be just as accurate as a medical-grade, FDA-approved pulse oximeter I have (one which does not have any smartphone app monitoring capability), which costs ten times as much as this unit. Given the fact that you can (effectively) "snapshot" the recording data (in real time, so to speak) using the Wellue app in order to exhibit later (say, by taking a screenshot, or simply opening the app and showing the previously-recorded data to someone) along with the very low price of this pulse oximeter, I think it represents an excellent value; the combined function of the Wellue pulse oximeter and its smartphone app is superior to any other product I've encountered.

Everything works as expected. It's a little thicker than none Bluetooth device. But the app has the irritating function of buzzing when the device is removed or turned off while recording a reading and can't be turned off. Which if you're taking a reading late at night or early in the morning the buzzing disturbs anyone in the room.

I love that I am able to check my pulse and oxygen at home. That has been very helpful for me to monitor. I love the feature that it sends the info to my phone and I can show it to my health care providers.

I love the app and features. The pulse ox works well. A bit tighter than my old one but it’s because it’s new and it does the job great. I bought two of them.

I've owned this for over two years. Purchased to have a bluetooth device so my phone could save my SpO2 and Pulse data. The Android and IOS apps work well. When my HR is less than 50 it sometimes indicates 2X the correct reading; an algorithm problem I guess.

Easy to use. O2 level and heart rate easy to read and appears to be accurate
