Review: Works well, great value. - My partner has Pulmonary Fibrosis which means her saturation levels can, and do, drop like a stone. She uses ambulatory oxygen when this happens. This O2 ring has been excellent for her. She uses it all day, and has the vibration alarm set so it buzzes when her SATs drop to a certain level, that she can set. She then plugs into her oxygen. At night, when she takes it off, she charges it up and uploads all the days days to her phone. Once you get used to reading the data, it is invaluable. Setting the ring up to the phone was surprisingly easy. At first I thought it was a bit expensive, but after a few months use, it has proven to be exceptional value for money. The accuracy is good, as has been tested against hospital equipment readings. The App is good. Ring is comfortable, albeit slightly bulky. Can't comment on battery life, but if it lasts one year or two it's irrelevant, I'll buy another one.
Review: Great product. Works well. - This is my second time buying the same device. The first one became faulty after two weeks, but customer support was very helpful in identifying the issue and provided a refund. Because it worked so well and fit comfortably on my thumb, I decided to purchase the same model again. So far, I’ve been using it for two weeks, and it has performed perfectly. It has only come off my thumb once. I’ve given it 5 stars for now—time will tell how well it holds up in the long term. I’ll continue to provide updates.

### ⭐⭐⭐⭐⭐ Excellent continously recordable monitor
*by S***M on 17 October 2025*

NOTE: I am using this device for peace of mind and evidence not as a medical diagnostic device. If in doubt see your GP. I have been having issues with my o2 levels while I sleep and have been using a standard wellue fingertip o2 monitor. This keeps falling off but I was getting better at it. I found this online and have been watching the price. It came on offer in the sale, so i snapped it up. It is simple to use, just pop it on your finger and link it to the app. It is tight enough to stay on without cutting circulation and vibrates loud enough to be noticeable. It does not beeps like the fingertip model. You can change warning setting on the app and the recordings are a little more detailed. Battery lasts all night and is recharged via usb-c cable Bottom line is I sleep better having this product
