Pros:
- Looks and feels like a quality smart watch.
- Super responsive screen and the display appears to be top notch.
- Samsung wearable app is clean and easy to setup.
Cons:
- requires you to download the Samsung health app but the app setup is garbage. It guides you towards enabling 2fa but either errors out or closes the app.
- you have to have a Samsung phone in order to use the ecg function.
Smart watches can be super gorgeous and built with the best specs, but if the required apps lead to a negative customer experience then the product is no good.
