[This review was collected as part of a promotion.] I got this as a gift 3 months ago and it works perfectly!I use it primarily for tracking my sleep and workouts to get an overview of my progress. The one feature I use the most (and is also the reason I got interested in the product) is the caffeine measurement. My sleep has gotten way better after limiting the caffeine consumption in regards to what the app says. Also a thing to note is that i got the ring with titanium coating and Im surprisingly amazed of how little the scratches are visible on the ring after 3 months use. Overall a great product!

[This review was collected as part of a promotion.] Its lightweight design is so effortless that I forget its there. The intuitive features have made tracking my habits second nature.

[This review was collected as part of a promotion.] Up until a week ago it was working fine, registering my values efficiently. After the latest update however, the battery doesn’t last a whole day anymore. When it was new I didn’t need to recharge it for approximately 3 days. I like wake up function (found a favourite tune) and I use it almost daily. I don’t have a second devise to compare the functions to so can’t really say much about its accuracy. However, I chose this ring above Oura simply because it doesn’t require a subscription to see the more complex values from recording your sleep. Another reason for choosing this over Oura was the aFib detection and cardiofunction, but I got quite disappointed from learning that these two functions require a subscription. On the plus side I like the layout and I find the info about all things it contains to be interesting.

[This review was collected as part of a promotion.] I bought the Ring AIR less than a year ago in December 2024 and I’ve been extremely satisfied and impressed with the insights available, especially sleep. However, in recent weeks, the battery life has absolutely diminished and I struggle to get through a single day without charging once or twice.
