The functions are amazing for an intermediate runner and sports person like me. It is a very comfortable, light and fun coloured watch that enables me to record my activities easily as it pairs with Strava. Also, the GPS is very accurate and the pace quickly corrects as you speed up or slow down. I love that it is only operated by buttons, it doesnt have a touchscreen, so I can use it with wet hands or gloves. The fact that the time is shown at all times on a dim screen is amazing as it gets rid of the need to awkwardly flick your wrist to see the time like with some watches( it also has an option to turn on light so the screen is visible in the dark or when its sunny!). The band is smooth and very nice on the skin as is does not rub or stick, even when sweaty, and stays in place all day. Lastly, the delivery was VERY fast and the watch came in the original box with not even a speck of dust on it. Even though it is my first sport watch it is definitely my favourite and I really recommend it :)
