## Customer Reviews

### ⭐⭐⭐⭐⭐ A very good health monitoring tool!
*by M***C on June 27, 2024*

I have been using this since new year’s 2024. Over the past couple of years I have been hospitalized for hypoxia a couple of times. All the pulmonologist and cardiologist after several days of a hospital stay couldn’t seem to figure out what was causing the problem. I have been trying to figure things out myself as much as possible. When doctors don’t come up with answers, you have to come up with your own. Constantly feeling faint, sick, dizzy, vision, problems, etc. I have learned not to let Doctors see this. Now while I was on oxygen, I had this on one finger and my primary care. Doctors on the other finger and they were both very very close and accurate. Some doctors are immediately dismissive when they see that you’ve been monitoring your oxygen, which I think is completely idiotic. This has helped me really advocate for myself, as I just recently was able to get a hole in my heart closed, diagnosed with three strokes, and a rare condition called Platypnea Orthodeoxia. Seeing how often and how much my oxygen is down in the 80s and the 70s even, I don’t even know how I function day to day, but most of my doctors don’t even want to see the charts that I keep on my phone from this. I have been a victim of medical gaslighting a few times even since the beginning of the year, because some doctors do not like to see people trying to figure things out on their own. When you know, something is wrong and you can prove it, they don’t like to be shown up I guess. My allergist just told me the other day that everybody’s oxygen drops. I highly doubt it drops enough for hospitalizations and strokes. I say if they’re so smart why haven’t they figured it out yet? This product works great for keeping an eye on things and seeing what triggers oxygen drops. Be careful of what healthcare professionals see you using it. They assume everything bought on the private market is worthless either that or they assume that someone who wears one of these is just a hypochondriac. Uploading data to my iPhone from the device is very easy to set up and to use. I would like to see sharing a little bit easier. One thing that could be improved on the product is the rubber part of it is a little too flimsy.

### ⭐⭐⭐⭐⭐ Doctor appreciated the blood oxygen level reports
*by A***R on May 6, 2024*

The device is easy to use and wear at night. I suffer from pulmonary hypertension and worry about low blood oxygen during sleep. The unit provides excellent information on drops in blood oxygen levels and changes in pulse rates during sleep. The data is very easy to download and print. I also use CPAP and the device gives me actual blood oxygen levels rather than oxygen ups and down as recorded by Resmed machines. Based on the information that I received from the device I began adding small amounts of oxygen from an oxygen concentrator to reduce oxygen drops into the 80% saturation range. I printed out recent reports for my pulmonologist at my last appointment and he was very impressed by the level of accuracy that is provided by the Wellue oxygen monitor. I would recommend the device to anyone who needs this information.

### ⭐⭐⭐⭐ PC software interaction
*by R***N on August 21, 2023*

Thank you Julia for your assistance.I did not realize there were 2 somewhat similar products - O2 ring and Oxylink ring. Turns out the Oxylink ring that I purchased is not currently able to work with PC software. But it works great with Android. And turns out soon(?) this WILL be able to work with PC software (no ETA given).Julia was very helpful and informative in assisting me with this situation. We exchanged several e-mails trying to get my ring to talk to the PC before realizing the confusion of the 2 products (I had called my ring the O2 ring in error). She was good about explaining the difference and was a pleasure to work with! Very good support.The ONLY reason I'm not giving this a 5 star rating was due to the confusion of two product names and not seeing any notice that the Oxylink ring does not (currently) work with PC software. Other than that, great product - it even fits on my big fingers with no issues and is easy to use.
