Vibeat S4 Rechargeable Pulse Oximeter, Bluetooth Blood Oxygen Saturation and Pulse Rate Monitor, O2 Meter with Free APP

If cost is primary objective this msy be ok. I find it uncomfortable and marginally accurate atBest

I am giving this device a four rating, pending my determination of whether the charging function works properly.In terms of measurement, this oximeter works fine for me, and I am starting to keep a digital record of my O2 level and pulse.The issues with these devices are battery reliability and some variation from one oximeter to another. Time will tell as to the battery. I left it charging overnight, and the device was still in charging mode when I returned to it. The instructions say it is supposed to go off when fully charge. I will update this review as I learn more about the charging factor.As to deviation, consistent use of the same oximeter provides higher likelihood that material changes in O2 level will be spotted. Use a different brand and your reading may be off by a point or so.My only present complaint is a defect in the instructions. A photo of the device appears in the tiny manual. Superimposed on the photo is a diagram naming and pointing to the various parts of the device. The photo is of poor quality and comes closer to being a blur than a photo. I could make out that an arrow was pointing to a part of the device which was said to be the USB port. Search as I did, and there was no usb port to be found. In fact, I eventually I found that there was a kind of blue rubber band, same color as the device, that circled the upper portion of the sides of the device, totally covering the usb port. I saw no mention of that band in the manual, even though a part of the band is permanently affixed to the device.

This is pricey and worth it if you need and use the features ot offers.The finger sleeve is rubber and feels comfortable on.The app tracks your readings both pulse and oxygen and keeps this information until deleted.Has a led display (could be brighter in my opinion).You can sync the information to Apple health and once that is set up it will automatically sync e wry time.You have the option to share your results with other /doctors (I have not figured out out to use this feature though).It automatically turn on when you insert your finger (if it won’t sync via Bluetooth I found it helps to power off and on to correct this).You connect the device through the app and not in your phone settings.It comes with a lanyard and a storage/carrying case.Instructions are not the best but okay.

This is a nice, wearable pulse oximeter. It is compact, lightweight and comfortable to wear. It uses a silicon duckbill sensor to slip over your finger instead of clipping on the fingertip. It doesn't get in the way much as long as you don't need to bend your fingertip. The accuracy seems good and generally in the ballpark as my trusty fingertip oximeter. The material and build quality is pretty decent as well.The oximeter automatically turns on when you slip it over your finger. The built-in display show your real-time SpO2 level and pulse rate, plus a pulse strength bar in the middle. The readings are updated every 4 seconds. It also records the readings in its internal memory. It can store four groups of 1-hour data, so that you can sync the data with your phone app later.The ViHealth app is pretty intuitive and easy to use. It displays your real-time oxygen level and pulse rate on the dashboard. You can review your saved data in time chart or share it. You can also set a threshold alert for the oxygen level so that the device will alert you when your spO2 drops below it.The only minor issue I have with this oximeter is that the display isn't very bright. It is readable when you are inside a building but not so outside in the bright daylight. The glare from the glossy screen top doesn't help neither. You can always use the app to view the real-time readings anyway.The oximeter is rechargeable via USB. A single charge can last up to 12 hours. It comes with a USB charging cable, a lanyard, a drawstring microfiber bag, app manual and user manual. It has a IP22 water resistance rating (a silicone surround covering the power button and USB port).Overall, I like this little wearable device. It is comfortable to wear and seems accurate. It helps me keep taps on my oxygen level and pulse rate over time. If you just want to take a reading of your SpO2 and pulse rate once in a while, an inexpensive fingertip pulse oximeter should suffice. If you want to track your readings over time, this little device gets the job done.

My mother doesn't own a smartphone. I manage all her smartwatch and oximeter data. I knew before going in that this device doesn't appear to have data to download, but it's really not that necessary.This device saves 4 two hour sets of data. The images with the data can be shared.What I didn't know is that more than one device can work from the same phone. That's not so with our smartwatches. I had to buy a different style of watch so that I could help her monitor her data. It's such a relief that I can check both her data and mine from the same phone.It doesn't seem like such a hard ask, does it? But, since it happens, I thought I'd mention it.Since she only wears it a few times a day for about an hour, the device lasts several days without needing to be recharged. It charges quickly.You can monitor the device from the phone and you can set up alerts on both the device and the phone, just make sure to turn your volume up.As far as accuracy, tested on two different people, both with different readings, and tested with different devices, I can only surmise that the device is accurate. At least, it's as accurate as the other device is.I used it when I was charging my oximeter. It alerted me to a low oxygen and high blood pressure issue while I was sleeping. Actually, my body did that, but the minute I woke up I felt it start buzzing. It wasn't far off from my body's own alert system.I can't tell you what a relief it is to be able to see things almost as soon as they happen. We can make corrections if we know what's going on.Bottom line: Would I order again? Yes. Would I gift? Seems like an odd gift, but yeah. If someone I knew needed one and I had the money, I'd gift it. Makes a good household gift. Perhaps with other things people don't usually consider until they need them...
