The watch is well-made, the design is unusual and so it's a matter of subjective opinion whether it's nice or not. The system is very smooth and stable – so far I haven't experienced any lag or freezing. The battery life is what you'd expect from a smartwatch for everyday use, so around 24 hours depending on usage (for anyone switching from a Garmin watch that you charge once every 10–14 days, this will be one of the main things to get used to), charging from 0% to 100% takes about 1.5 hours. The interface has a nice design, it's fast, smooth and intuitive. You can navigate the menu using standard gestures and scrolling, similar to on a phone, or you can use the software bezel (by swiping your finger along the edge of the watch face) to scroll through apps, which works with good responsiveness. Pairing was hassle-free, even with a non-Samsung phone (OnePlus) – the connection is made using the Wearable app, which, in addition to pairing, is also used for all sorts of watch and app settings. As for apps – there are pre-installed Samsung apps (I consider it a minus that you can't remove the Samsung apps you don't use). The range of 3rd party apps is rather small – the basic Google apps are available as standard (Gmail, Keep, Maps, Google Wallet, YT Music) – the compatibility is very good. However, with the basic apps on the watch and the available 3rd party apps, all the fundamental needs for daily use are comfortably covered. Notifications from apps on the phone work regardless of whether you have the given app downloaded on the watch; they are easy to browse and are clearly sorted by app (so it's not just one list of notifications from all apps, but each app has its own list of notifications that you can easily swipe between). The apps for tracking activities and sports are clear and intuitive – they automatically detect the start of an activity, and if you pause the activity, the tracking stops until you start the activity again or end it completely. The resulting summary is nicely graphically processed, including a plot of the route on a map using GPS (there are slight inaccuracies in densely built-up areas or in the woods), and more detailed information about the activity is also available, which will be sufficient for the average person (average speed, heart rate, heart rate zones, calories burned, cadence, etc.).
