Overall Rating Snapshot

I can leave my phone at home.
The Apple Watch has been a real jump in technology and function. Just as the mobile phone freed me from the home phone or having to carry a wallet, the Apple Watch has freed me from my mobile phone. There are some other features that I really like. I can make and answer calls and texts without having to find my phone. I can see the UV index. I can keep track of my heart rate during exercise. I get reminders to stand up throughout my work day. I can easily control podcasts and music. The watch looks good. The band is very functional and comfortable. I am really happy with my purchase.

Overall review
The quality of the service and online was really good ztzff were really helpful at good guys. The watch was a great price and was able to get price matched with another online store. The watch charges reasonably quick and lasts a couple of days. The watch is great when the kids steel your phone so you know exactly where the linked phone is to not just a bing but actually go this way etc. My husband was very happy with his watch and the health features it had.
