Perfect basic smart watch
I wanted to start with a cheaper smartwatch to see if I'd like it before upgrading to a larger one later. Im so happy with the Fit3 I don't think I need to upgrade. It shows notifications, alarms, sleep and step tracking with heartrate monitoring as well. Really easy to use and a solid battery life means it's replaced my old watch as my daily driver! Would definitely recommend, it has probably 80% of the features of a more expensive smart watch at a fraction of the price.

Best value fitness band !
Compact size, comfortable fit, third party straps are much better for comfort, plenty of battery to last almost 5-7 days. Beautiful display. Responsive screen, accurate steps and HR monitoring. Good for phone call notifications too. Also Samsung health app is really clean and easy to use. Overall a great buy at $79 on sale 🙂. Would have even paid $100 now that my mum, wife and MIL all have this watch and love it !
