WearpulseContinuous Wrist Pulse Oximeter, Blood Oxygen Saturation Monitor with Smart reminder, Bluetooth, 72 Hours Endurance Tracking SpO2 and Pulse Rate, Checkme O2 Max with PC Software & APP

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.

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.

I have severe sleep apnea and use a BiPAP with high pressure settings because of frequent blood oxygen desaturations. My doctor advised that I monitor SpO2 levels during sleep and keep an ongoing record of the results. I previously used the Wellue O2 ring for this purpose. The advantage of this particular ring is that it syncs to the SleepHQ application I use to monitor my BiPAP statistics. Unfortunately, I have gone through two of these expensive rings because of durability issues. The first failed when the rubber ring band broke and the second simply died. Both problems occurred shortly after the one year warranty expired.I purchased the Wrist Oximeter primarily because the ring fingerpiece can be replaced for a reasonable price without having to buy and entire new unit.I find this wrist oximeter to be easy to use, comfortable to wear, and the display is very clear and legible. I download the results on both the iPhone software (which occurs automatically as soon as the device is removed) and on the pc software (which occurs when I plug the device into my computer for charging).I appreciate the vibrating alarm which wakes me when my SpO2 drops to a preset level so I can make adjustments to my CPAP mask. The vibrating alarm also does not disturb my wife.While the software does not have the ability to sync the results to the SleepHQ program, it does sync to OSCAR, a similar program. Thus, I am still able to monitor my BiPAP therapy and the effects of apnea events on my SpO2.I do have some negative issues. First, I find it difficult to attach the watch band on my wrist because of arthritic fingers. Second, the software only records events on a daily basis. It would be helpful if it would include weekly, monthly, yearly, and custom periods of results so that trends could be monitored and provided to physicians. Third, I worry about durability issues like I had with the Wellue ring and concerns that this device will also fail shortly after the one year warranty expires.

While this device is of great use to a person like me who is on oxygen 24-7 it failed in less than 30 days. The warranty service is completely useless. I would have to ship it back to Hong Kong by express shipping and then they would decide to do.
