as a chef who's always on my feet, i bought this to keep track of my health and stay connected. i've been using it for over six months now, and while it does the job, it hasn't wowed me. the waterproof part is a lifesaver when i'm washing up or caught in rain, but the heart rate monitor seems off sometimes, making me doubt its reliability. the bluetooth calling is convenient, but the sound quality isn't great, and it drains the battery faster. overall, it's okay, but for someone who hunts for deals, i feel i could've gotten something better. not terrible, but not amazing either :)
- Pros: it seems quite useful for my fitness routine with the heart and blood pressure checks, and i like that it works even when wet, which is handy for my active days. the manual was helpful in setting up the bluetooth calls, so i can talk without my phone nearby.
- Cons: the design feels a bit bulky on my wrist, and the readings for health metrics don't always match what i get from my other devices, which is disappointing. i expected better accuracy for the price, and the battery doesn't last as long as i'd hoped.
