As an entrepreneur juggling a lot, I bought this as a gift for myself to stay on top of things, and my first impression was pretty positive. The courier called ahead for delivery, which was a nice touch and made it easy to get. It feels durable and stylish, blending well with my home and garden interests by not looking too techy. The health features are a good motivator, though not perfect, and the calling function saves me time when I'm busy. Overall, it's a solid choice for the price, but there's room for improvement in reliability and battery performance.
- Pros: I was fairly impressed with how well this watch handles getting wet—it's been through rain and even a quick dip without any issues. The ability to take calls directly from my wrist is super convenient, and the heart and sleep tracking features have been helpful in keeping an eye on my health without being too intrusive. Plus, the gold finish looks sharp and adds a nice touch to my daily wear.
- Cons: The battery life could be better; I find myself charging it more often than I'd like, which is kinda meh for something I rely on daily. Also, the initial setup was a bit fiddly, and I could be wrong, but the accuracy of the sleep tracker seems off sometimes, making it hard to trust fully.
