I'm very impressed with this watch from ZenWatch. Not only does it have a modern design, but the health features like blood oxygen level, blood pressure, and ECG monitoring work well. It's easy to use and syncs quickly with my phone. The heart rate tracking and abnormality detection are especially responsive. The battery life is solid too; one charge lasts almost an entire week. Overall, I'm very satisfied with ZenWatch's quality!
