Continuous Wrist Pulse Oximeter, Blood Oxygen Saturation Monitor with Smart Beep, Bluetooth, 72 Hours Endurance Tracking SpO2 and Pulse Rate, PC Software & APP

This continuous wrist pulse oximeter provides second by second O2% allowing me to use the ViHealth App and the SleepHQ App to see what happens to my O2% during my sleep apneas. My Apple watch only samples my O2% every minute or so rendering it incapable of helping me understand what is happening during an apneas. You need the continuous second by second analysis. I plot each breath taken with my ResMed C-Pap machine along with my O2% from my wrist pulse oximeter using the ViHealth and SleepHQ Apps. I am able to see each apnea and what happens to my O2% when I awake each morning. Using this information, I have significantly reduced my apneas and I know exactly what is going on with my O2% during my sleep. I also use this device for tracking my O2% when walking up a steep hill at a fast pace. I set up my device to show continuously on the display so I know when the O2% when walking and I plot it out along with my heart rate on the ViHealth App. I am so happy with this device. It does everything I was looking for and is very accurate. I like the wrist unit combined with the thumb sensor. It is easy to use and easy to charge. Carl Bullock

I'm a borderline sleep apnea person and have used their previous model for almost five years before the lithium battery died. I have used this new model for about six months without any problems. It is easy to wear and the software app works very well. I showed my doctor at my last physical and he was impressed with the daily graph results. I like the variable vibration alert device and the variable settings on the oxygen and pulse levels. I set mine at 80% on oxygen rate and 50 pps heart rate. I rarely get a notification below these rates. It takes less than one to two hours to charge the larger lithium battery that lasts much longer than their previous model at about four days depending on how long you wear it each night. Overall, I'm happy with this model and very easy to use! One thing I learned is too keep my weight and BMI down which has less sleep apnea problems.

Unit performs as expected. Bright, clear display for easy reading. Display shuts off when in use with probe. Button push turns display on for about a minute. Button is on side of wrist module, so can't easily trigger it while sleeping. Vibration alerts to O2 deficit (adjustable). Strap on wrist unit is a little challenge to latch, but it holds fine. The remote sensor slides over finger to wear like a ring. Relatively small for a thumb, but fits fine on my fingers. Self-tensioning silicone design. Able to hold continuous data; can be downloaded for reports or import to OSCAR. App is a little klunky for directing data, but it integrates to OSCAR fine. Quality was really a problem with this item. I bought one just before Christmas and it failed (wouldn't turn on) within two months. I returned it and got a replacement from Amazon (the manufacturer never responded to my email). The second unit just failed, after only about 7 weeks. I contacted Amazon and they were kind enough to refund my purchase because I was afraid to just do another replacement. Very disappointing, since so many aspects of the device were attractive. In the end, if it doesn't last, it isn't worth it.

I have had 2 of the Wellue O2 rings which both had failed so I was reluctant to try the Checkme O2 Max but decided to give it a try. I have found some favorable results as well as some I think could be improved. The wrist band is comfortable, the display is very legible and has an easily access control button. The extended 72-hour battery is great and downloading the readings is very easy to either your PC or phone and has very easy to understand charts. The charts are good enough to share with your doctors. Some issues that could be upgraded or changed are as follows: use a different charger connector to a more common one used. I had found the wrist band to be somewhat challenging to clasp. Accuracy seems to constantly be 1 to 2% less than my other finger monitors. I initially thought I would return it but decided to keep it after I learned how easy it is to use. Perhaps there is a updated program download which could resolve the accuracy issue.

The product in theory works great. I have small hands and wrists and the device does not fit well. I would prefer a standard watch band clasp to the two prong snap. It's difficult to get to snap with all of the excess band. The ring doesn't fit well. I tried it on all of my fingers and it seem to push my finger out of the bottom. It would be nice if there was an option to request a a ring size with a full ring band. Also I'm not loving the cord that connects the ring to the device. It's too long and there is no good place to put the excess. I'll give it a bit longer, but I think I'm going to return it.

I chose this Check-me product, upgrading from the other product that attaches to the finger, because of the possibility of recording blood oxygen values ​​and heart rate over 10-hour periods, enough to cover the entire sleep period and for higher battery capacity. The measured blood oxygen values ​​are two to three percent lower than the actual value compared to a medically certified Oxipulsometer, but the values ​​remain constant and the heart rate measurement is accurate. It is very practical and easy to use, and the application on the phone contains many possibilities for setting and informing the records permanently saved from the device in the application via the Bluetooth connection. It has the ability to send the "Activity Report" during sleep and beyond, by e-mail in PDF format and even to the printer for printing, excellent functions. This product pairs with another product namely "Omron Complete" to have an overview of personal health. I am satisfied with the purchase and recommend it with confidence.
