## Description

Product Description

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.
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.

### ⭐ Not up to the job
*by D***G on 21 June 2026*

Only had this 3 days and it's stopped working. I remove it when washing, but wear it continuously the rest of the time. I loved it at first, but found it far too tight on any but my pinky finger, however I am overweight. The concept behind it is brilliant, I've been suffering from shortness of breath and a strong cough for about 2 years now, and this device was perfect for heart rate and blood oxygen level recording. The app works well, as does the PC software, which allows you to download the data graphs in pdf format, very handy to show to my doctors. Ring is a bit chunky, but you quickly get used to it, and it doesn't really get in the way. Battery life is, as stated, about 24 hours, but if you consider that you have to plug it in to charge, and download data every day, I don't think it's up to it, hence only lasting 3 days. My concern is that it's not up to the job, because you can wear it continuously but it's not waterproof, meaning that if you wear it for workouts and the like, you'll sweat and it may be damaged. Mine suddenly started vibrating strongly and I couldn't turn it off, I had to wait till the battery died, but on plugging it in to charge it began vibrating again. I left it for 20 minutes and it then turned on, and I was able to connect, but it randomly disconnected. At one point it displayed a countdown ending with a power switch icon. Since then it shows a flickering display and won't connect.
