When abnormal Oxygen Saturation or Heart Rate are recorded, the alarm in the older models was vibration, in the latest model it is beeping noise waking up your sleeping partner too, a big disadvantage, and a reason not to use the alarm. Wish the vibration alarm is included as an option

It is very straight forward and easy to use whether you have experience with medical devices or not. This device fits well, including on my large and rather thick fingers, and stays in place for prolonged use so long as you are not moving your hands under your pillow a lot while you sleep. It can track up to 4 10 hour continuous readings, and has awesome battery life for its size. There is an app that you can download to sync the device with your smart device to upload the readings. This allows you to monitor and review your readings and you can share the chart with your doctor. Overall, this is a great pulse and blood oxygen monitor that is comfortable and convenient to use whether you want to periodically check your readings or monitor on a continuous basis.

I have low oxygen and use oxygen at night. I love that you can set it to beep if O2 Sat drops too low. It can all be controlled from my phone. I love the software that comes with it. Easy to use. Good quality. It is comfortable and easy to read.

Wonderful to be able to track my oxygen for the whole night. Very comfortable and the app I'd easy to use.

Great product. Setup was easy and provided me the ability to sleep without worry that my loved was struggling to breathe without my realizing. Would recommend to anyone needing to monitor a loved one.

It fast acutely shows heart rate and saturation use it for work

If you check your pulse or blood oxygen level at home you likely have the type that clamps onto the tip of your finger which isn't uncomfortable but also makes it so you cannot track these rates while doing anything else because it won't stay in place. I love the design of this pulse oximeter because it wears on your finger securely and makes it so that if you wanted to wear for a prolonged period of time you could do so while still doing other things! Perfect if you need to track heart rate or blood oxygen levels throughout the day instead of just one quick check in.

My experience with the Wellue customer service was extremely well!!!!

I use it to track my oxygen levels at night. It appears to be accurate, registers the same as my fingertip pulse/ox. Doesn't take long to charge. I really like it!

Too cold to test outdoor, gloves needed! More to learn when temperatures get higher!!
