Smart Bracelet
Gregory N.
Seattle, WA
June 6, 2025
As a chef and barista in Seattle, I'm always on my feet, so I picked this up hoping it would help me keep track of my activity without being a hassle. The courier called ahead for delivery, which was polite, but I've only had it for a week or so. The display is crisp, and I appreciate that it syncs easily with my devices, but I'm skeptical about how well it really monitors things like heart rate—it seems to jump around a lot. For paying at the coffee shop, it's convenient, but overall, it feels like it might be more style over substance. Still, it does the job for now, and I'll see how it holds up over time.
- Pros: The screen is incredibly sharp and easy to read, even in bright light, which is a relief for my old eyes. I like how it connects to my phone without any fuss, and the payment feature is handy when I'm out and about without my wallet. It holds a charge for a long time, so I don't have to worry about it dying on me during a busy day.
- Cons: It seems to run hot sometimes, which is a bit annoying, and the heart rate tracking feels a bit off—maybe it's too sensitive or not accurate enough for my liking. The design, while sleek, might be a tad too flashy for someone my age, and I wish it had more practical features for my daily routine.
