Decision:

As a perfectionist dad in Montreal trying to juggle work and family life, I picked this up hoping it would help me stay on top of my health goals without breaking the bank. I've been using it for a couple of months now, and it's mostly been a solid companion. The display is a real standout—I can glance at it while cooking or chasing my kid around the park, and it's always legible. Battery life is impressive; I only need to charge it every few days, which is a huge plus for my busy schedule. But there are quirks that bug me. The music feature, which I was excited about, often glitches and skips songs, making my workout playlists unreliable. Calls are another letdown; I've had a few where the other person said I sounded like I was in a tunnel, which is ironic for a device meant to keep me connected. Compared to others in the same price range, it does the basics well but falls short on the extras. It's not a total disappointment, but it leaves me wanting a bit more polish. For now, it gets the job done, but I might upgrade if something better comes along. 😕

• Pros: The screen is incredibly clear even in bright sunlight, making it easy to check my stats without squinting. It connects to my phone quickly and stays linked without dropping out, which is a relief when I'm on the move. The battery lasts for days on a single charge, so I don't have to worry about it dying mid-day, and it handles getting wet just fine, surviving accidental splashes without a hitch.
• Cons: Most likely, the music playback feature is a bit clunky and doesn't always sync well with my playlists, leading to some frustrating moments. The call quality can be hit or miss, with voices sometimes sounding muffled or distant, which isn't ideal for important conversations. It feels a bit bulky on my wrist, and for someone who prefers precision, the fitness tracking seems to overestimate my steps or calories burned at times.
