Giving up on smart rings
After about a year of wearing a smart ring, I've decided to throw in the towel.
I did really like my Oura Ring. Tracking my sleep and steps, amongst other things, has been really helpful for my health journey. Symptom Radar was also typically pretty accurate and usually let me know I was about to get a cold even before I noticed the symptoms.
But a smart ring has a few major downsides that a wrist-based device doesn't, and they weren't obvious to me when I first bought mine.
Turns out your fingers store quite a bit of fat, and if the fitness-tracking device helps you successfully lose weight, the ring might no longer fit. I initially bought an Oura Ring in size 13 when I was around 94 kg. Then I lost about 14 kg and it became really loose. After picking up a new sizing kit for a replacement device, I learned I was down to a size 11.
Your fingers also change size with temperature. Cold makes your fingers smaller, whilst warmer temperatures do the opposite. Oura's product guidance says that finger size also fluctuates with food and drink, exercise and altitude.
Many exercises, from pull-ups to the bench press, place the ring between your hand and a metal bar. Oura recommends removing the ring during activities that involve friction, including weightlifting, to avoid scratches. For me, tracking workouts was one of the primary reasons that I bought it in the first place.
Rings are constantly exposed while washing your hands, showering, cleaning and gripping things. Even when the ring is water-resistant, water and soap can become trapped underneath it, so removing, drying and replacing it becomes another small source of daily friction - something I repeatedly forget to do, which might explain how I ended up with 2 broken devices which I explain below. The outer surface is also easy to scratch. Oura's care instructions acknowledge the issue of both trapped moisture and scratching.
I must admit, though, the catalyst for these realisations about smart rings was that both my original ring and its replacement stopped working. Bluetooth would connect, but neither ring would track anything, as if I wasn't wearing it.
The first ring stopped working around the same time it stopped fitting me, and a newer model had come out anyway, so I begrudgingly replaced it.
But the replacement stopped working just two weeks after I got it. Thankfully, Oura were willing to offer a refund for the second ring. I think I was just unlucky, and I'm really not trying to throw the company under the bus, but it made me take stock of wearing a smart ring and realise these downsides.
