Cardiff
June 5, 2025
As a stay-at-home dad in Cardiff, I got this watch to help keep organized and stay active with my kid. I've been using it for a couple of months now, and it's been decent for tracking my steps and heart rate during walks. The display is sharp, and I appreciate how it handles calls and messages without fuss. However, I'm a bit disappointed that it doesn't hold a charge for more than a day, and some features feel unnecessary for my simple needs. It's functional, but not perfect—I'd recommend it if you're on a budget and want something basic. 😕
- Pros: The screen is incredibly clear and easy to read without straining my eyes, which is great for quick glances while managing things at home. I like that it connects smoothly to my phone, so I never miss important notifications, and being able to make payments with just a tap is very convenient when I'm out with my child.
- Cons: It could be wrong, but I find the fitness tracking a bit overwhelming with so many options; I mostly just want to track basic activities. The battery life isn't as long as I'd hoped, needing frequent charges, and it feels a bit bulky on my wrist during daily wear.
