I expected this watch to be a real beast for keeping up with my fitness and daily tasks, but the reality fell short. The sleep tracking gives inconsistent data, and I find myself double-checking everything. For the price, I thought it would perform better, but it's just okay—not something I'd rely on heavily. :)
- Pros: I liked that it feels sturdy and can handle some bumps, which is good for my active days. The wireless charging is very convenient, and the ability to take calls without my phone is a nice touch when I'm out in the garden.
- Cons: The health tracking could be wrong often, with heart rate readings that don't match my expectations. It's not as reliable as other watches in the same price range, and the battery life drains faster than I hoped, making it less of a beast than advertised.
