As a dad trying to stay healthy for my kid, this ring has been a decent tool. I've been using it for a couple of weeks now, and it's been pretty good overall. For tips, I'd say make sure to charge it regularly with the case to avoid running out of battery unexpectedly, and maybe double-check the health data with another device if you're really focused on accuracy. It could be wrong sometimes, but for the price, it's a solid choice. I appreciate that there are no hidden fees, and it works with both iPhone and Android, which is convenient. If you're into fitness and want something simple to monitor your health, this could work for you, though it's not perfect.
- Pros: I found it pretty good for keeping an eye on my sleep and health without any extra costs, which is very helpful for my fitness routine. The battery lasts a long time, and it's comfortable to wear all day, even during workouts or swimming, since it handles water well. The app gives clear advice and tracks things like heart rate and blood pressure accurately, which helps me stay informed.
- Cons: Sometimes the readings could be a bit off, and I wish it was a bit more precise, especially for sleep tracking where it might not always catch the deep sleep phases correctly. The design is thin and light, but it feels a bit fragile, and I'm concerned it might not hold up over time with my active lifestyle. Also, syncing with my phone isn't always seamless, which can be frustrating when I'm trying to check my stats quickly.
