Sleep SPO2 Ring Sensor, O2 Ring Probe for CheckmeO2 Max, Visible Oxy, Oxiband & SleepU

Good second source for Welle SleepU Sleep O2 Ring Probe.
I’d used Welle SleepU Sleep O2 measurment device. The device works excellent for its original purpose. However life of the Ring Probe of the device is not forever. My case, it became mulfunction in three years. That means about 1200 on & off, total measurement time was approximately 8,000 hours. Good life! Welle provide replacement for it cost $69 or so with USB cable. Not too expensive, but this Wearplus Finger Ring Probe is fully compatible with it (including measument data accuracy), but $ 28, less than half. Bottom line: Good second source, just buy, use it.

It’s working good
It works great

It’s the weak link ruining a good idea
This ring on a wire is the weakest link.It is a very weak link.The original lasted many many months.The replacements suck when they work at all.I write this in the middle of the night after being blasted awake _again_ by the alarm from a failing ring on a wire.I have lost so much sleep from this thing I contermplate the unmolested ‘forever’ for relief.If you are reading this and your original just failed I suggest ordering replacements 2 at a timeif you do not want to be without frequently.I’ll get another all in one compact “SpO2 Ring” with it’s shorter battery life.They fail too! by breaking in the thin part but can be ‘repaired’ with a band aid to keep it on a finger.You have been warned!

Always plug these into the monitor as soon as purchased. Often defective.
It’s easy to return if you bought them from Amazon and they quit within the first 30 days. Once I bought 3 and one of them didn’t work straight out of the package. I didn’t know for months because I hadn’t checked it when I bought it.I’ve worn the CheckmeO2 Max and Wellnue Oxygen Monitors for almost 3 years. They are expensive monitoring devices but the thumb rings they come with are junk. I keep buying them because the Monitors are unbeatable and this thumb ring is the only one that fits with my device.. Water shorts them out. Never use them when you are gardening or doing strenuous activities with your hands.Most all of the problems with the moniotrs, stem from the thumb rings. Error 4 displaying on the monitor is the most obvious. The red light in the ring flashing is another. I have a Check me O2,and can not speak to the other monitors but he display on my device shows a thumb ring when I plug the ring into the micro connection. When I put the ring on, my device flashes a heart with dashes until the monitor picks up and gets enough data points to display readings. If it behaves differently, consider it a RED Flag.I usually buy 2 at a time. One of the ones I bought this time was flashing and showing the heartbeat before I even put it on my finger. It started working okay after I put it on but I’m very weary it’s defective. I’m wearing that ring first because if it’s bad, it will go out before the 30 days are up.
