Review: Great product, great service - I wear my monitor 24/7, because my desaturations are sporadic, so I never know when my oxygen will drop. It works beautifully! Can't say enough good about it. Because I wear it 24 hours a day, the fingertip sensor eventually wore out. Since it was within the 1 year warranty, the company immediately replaced it free of charge. Great service from Zoe at Viatom! I purchased another unit so I can have one set for day time (warns me when I drop below 95 so I can adjust my activity or my oxygen settings) and the other for night. I have the night one set to warn me if I drop to 91 or lower. One unit charges while I'm wearing the other. It has been a lifesaver! The printouts have given my doctors so much insight on exactly what is happening with my oxygen and heart rate. Regarding some of the negative reviews: Some users don't seem to have their information right. The display light "sleeps", so it doesn't shine all night. If you need it to wake up, you just move your wrist. The red light inside the sensor ring is the same as any oximeter. It doesn't bother me, and if it did I would put my hand under the covers. I use the computer app and save the readings as a pdf so I can send to my doctor if needed. Have never had an issue with the computer app, and it gives you a 10 hour summary and then a 5 page minute by minute breakdown. It only stores 4 readings, and each time you take it off, it starts a new monitoring period, so if you take it off a lot you will need to save your monitoring more often. The drawbacks that I agree with is that it is very sensitive to motion (it also monitors and records your motion), so I was disappointed that it would not usually record while I was walking or moving around much. But I can type on my computer, and it records just fine, and it also records all night without a problem. I wear mine 24/7, so the finger sensor did wear out, but it has a 1 year warranty, so I got a new one for free. I really can't say enough good about this device. A finger oximeter only gives you a snapshot of what is going on. This gives you 24/7 what your oxygen is as well as your heartrate, so you can see what is happening in response to different activities and be warned if you are falling to unsafe levels. Highly recommend!
Review: Update - Update: great while it last, the connector broke within 5 months of starting using it. This sensor is accurate and helps treating sleep apnea as you can set up a vibration when your oxygen drops below a threshold. Two downsides: 1) the mini UBS connection isn't the greatest option as it is hard to connect and require directionality, it will be much better if they offer an easier self locking connection, and 2) the sensor ring is too small and I have to wear it in the little finger.

### ⭐⭐⭐⭐ Accurate, but not very practical to use during sleep
*by A***M on April 11, 2023*

The Good - THe device performance is good, the measurements are on the spot. - The reports are great and usable The Bad - The light on the device turns on every time you move your hand, sometimes is on your face - The downloads gets stacked sometimes, and you need to wait to charged to try downloading again - The battery only lasts 16 hours, basically needs to charge every other day - The connector is Micro USB, which is not long lasting in my experience with cell phones. And needs to be Plugged and unplugged for charging... I wonder how long is the actual usable life of the device. - The cable seems to be too long and sometimes gets stacked. They should provide two options at least. Performance is good, but, I think for a $175 device, the quality should be better
