As someone who works in healthcare, I was hoping this would help me keep an eye on my health metrics without breaking the bank. Before using it, I relied on basic pedometers and occasional clinic checks, but after trying this for a couple of weeks, I'm disappointed. The tracking for fitness and sleep seems off, and while it's nice that it's durable and waterproof, the core functions just don't deliver accurate results. It's a shame because the idea is great, but in practice, it falls short for serious monitoring. I might stick to my old methods for now. 😕
- Pros: The packaging arrived intact and on time, which was a good start. I liked that it doesn't require any extra payments to use the app, and the battery lasts a long time between charges, which is very convenient for daily wear.
- Cons: The heart rate and blood pressure tracking seem very inaccurate compared to my medical devices at work, often showing numbers that don't match up. The sleep analysis feels unreliable, as it doesn't align with how rested I feel, and the app can be confusing to navigate for someone not tech-savvy.
