Sleep & Fitness Tracker Smart Ring
Alexander S.
Victoria, BC
April 17, 2025
I bought this thinking it would be a game-changer for my health, especially with kids keeping me on my toes, but the reality is a bit underwhelming. It does track sleep stages and activity, which is helpful, but it's not as precise as I'd like—sometimes it misses my intense cycling sessions or misreads my recovery. Compared to other options in the same price range, it feels like it's missing some smart features. Still, it's decent for beginners, and I appreciate that there are no extra fees. I might keep using it, but I'm not fully satisfied.
- Pros: From what I feel, the ring is not bad at all for tracking my sleep and activity—it's like having a little coach on my finger that reminds me to move more. I liked that it's water-resistant, so I can wear it while cycling or even in the shower without worry. The build feels solid, and it's comfortable enough that I forget it's there most of the time, which is great for daily use.
- Cons: BUT, it's too basic for the price range—I expected more detailed insights, but it just gives general scores without much depth. The stress tracking seems off sometimes, and it doesn't sync well with my other devices, making it a bit frustrating. Also, the battery life is shorter than I hoped, needing a charge every few days, which is annoying with my busy schedule.
