Fitness Tracker Smart Watch
Zachary W.
San Antonio, TX
April 25, 2025
as a guy in his late forties who drives for a living and likes to stay active, i bought this watch thinking it would help me keep track of my fitness without any fuss. i was hoping for something durable and practical, and it mostly delivers. it handles my daily runs and hikes well, and i appreciate that it works with my phone without issues. the battery life is a real plus—i only charge it every week or so, and it holds up. it's not perfect, though; the size can be a bit much, and the sleep tracking isn't always accurate, but overall, it does what i need. for the price, it's a solid choice, and i'd recommend it to others who want a reliable fitness watch without breaking the bank.
- Pros: i expected it to just tell time and maybe count steps, but it's way more. it tracks my heart and how well i'm breathing, which is great for keeping an eye on my health during workouts. the battery lasts over a week, so i don't have to charge it all the time, and it works fine when it gets wet, like in the rain or if i splash it. i can change how it looks on the screen easily, and it lets me talk on calls without pulling out my phone, which is super handy when i'm driving or busy.
