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

It worked immediately as a replacement for a failed sensor with our BodiMetrics O2 Vibe Sleep & Fitness Monitor. This was especially appreciated since BodiMetrics discontinued the product and replacement sensors were no longer available from them. Thank you!!!

I bought the SleepU 4060 about 3 years ago, and the Wellue Checkme 02 Max 6060 about 4 months ago for the longer battery life.I have Central Apnea that triggers Cluster Headaches (not Obstructive Apnea, that a CPAP would be used for) and this is the best treatment I’ve found in 20 years.Anyhow, wearing it nightly, the Wellue sensor wire broke at 4 months, so while waiting for warranty replacement, I bought this one - works perfectly, including vibration alerts.I also tested it on my SleepU, correct O2 readings and vibration alerts too, nice!Please note - if your wrist-O2-monitor unit doesn’t offer vibration alerts, buying this isn’t going to add that feature to your monitor… you need to upgrade to an O2 monitor that has that feature already. (You might notice that some others have given negative reviews- please be cautious of their misunderstanding, as I know the Wellue is available without vibration alerts for much less - ensure you have the correct monitor first, if you expect vibration alerts.)

It works great

it works like the original. nice strong buzz when alarming. The weak point seems to be where the cable leaves the sensor housing. I've had two of the sensors fail from wear and tear on the cable at the sensor end. It needs a bit more silicone flex sleeve where it flexes as it leaves the sensor. The last one lasted a about a year and a half. It seems to me it sould last longer than that.UPDATE: In use for just at one month, the vibration has failed. It still seems to read and record accurately, but the vibration has completely failed. ANOTHER UPDATE!!! It seems that not only am I a sleep walker I am a sleep tech user. I apparantly got into system settings and turned off the vibration setting . Just on a gut feeling I checked those settings this afternoon and found that the vibration had been disabled. When I enabled the vibration everything worked as it should. My BAD!!!

This sensor fits well and reads well, but I just discovered after several months of use that the alarm function only emits a faint sound instead of the robust buzz that is needed. As a result, I would get many alarms in a row (the black triangles in the graph) whereas a working alarm would only need to alert me once or twice to break a low SpO2 cycle.

Service has been outstanding when I request a warranty replacement, they are warrantied for 1 year.I am curious about the negative reviews on not working, as I am super hard on mine. I workout, cut wood, work on cars etc. I wear mine 24x7Mine do fail though like clockwork at the 3-4 month mark with big drops, and random readings. SO I replace them when they start doing this and double check against my medical grade oximeter.I was hoping the new style sensor would fix that, but same problem. I suspect its tension in the bandIn either case, they've always replaced mine quickly, so from a service side, I have nothing but praise.

I received this item, though got black charger piece first, then 5-7 days later, got grey finger sensor o2

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.
