Smart Ring with Sizing Kit

so i got this ring a couple months ago to help with my fitness goals, and it's been okay. i was wondering, is it worth it? well, it does track a lot of things like sleep and calories, which is nice, but i've noticed it's not always accurate. for example, when i'm driving my car, it might count steps or something, which is annoying. the battery life is decent, but i have to charge it every week or so. overall, it's a helpful tool, but it could be better. i'd say it's a game changer in some ways, but not perfect. if you're looking for something reliable, this might work, but don't expect miracles.
- Pros: i quite like how it tracks my sleep and heart rate without needing extra fees, and the battery lasts a good while with the charging case. it's durable and waterproof, so i can wear it all day even when i'm out and about. syncing with my health apps is smooth, and it feels comfortable on my finger.
- Cons: the sizing was a bit tricky to get right, and sometimes the data seems off, like it could be wrong on steps or stress levels. it's not as precise as i hoped for a perfectionist like me, and the app could use some improvements for better insights.
