Customers say
Customers find the blood oxygen monitor easy to use and read, with a nice display and good value for money. They appreciate its monitoring capabilities, with one customer noting it’s particularly useful for remote doctor consultations. The accuracy and Bluetooth connectivity receive mixed reviews – while some find it consistently accurate and easy to couple with phone apps, others report inaccurate readings and lack of Bluetooth support. The data recording capability and oxygen saturation levels also get mixed feedback, with some customers reporting it doesn’t record all night and showing lower levels than actual readings.

Great for people that have to take their pulse frequently
I picked up the Wellue pulse oximeter recently and I’m really impressed. Setup was quick and simple, and the readings come up almost instantly. Compared to the ones I’ve used at doctors’ offices, the numbers match up really well — so I feel like I can trust it.I deal with POTS, and this has been a game changer. Not only does it give me quick, reliable readings on my oxygen and heart rate, but it also connects to an app on my phone. Everything records straight to the app, which makes it easy to track patterns and share with my doctor — either by showing them directly or sending the report.The screen is bright and easy to read, it’s comfortable to wear, and the automatic shut-off saves battery life. Overall, it’s a handy little device for anyone, but especially if you’re managing POTS or another condition where frequent monitoring is important. Highly recommend!

Sufficient functionality, excellent value, and fit for purpose
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.

Mary Burriss –
Work perfectly
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.

caution: sometimes reads 2X my actual HR
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.
