To be honest I did not want to spend the $400 for a watch that I may or may not use especially after spending $800 on the iPhone 7. After doing some intensive research, taking a few trips to the store and getting some input from relatives that owns it I decided to try it. I now use it everyday because of the activity tracker and the ease of checking my notifications. I'm sure there are much more to know about the features so I still watch YouTube and read reviews to learn new things. I had a free Geek Squad setup but it was never offered to me when I picked up the watch so I never went back or called about it. The watch do not look big even though I purchased the series 2 in the 42mm case. I'm very careful so my watch is still in great shape but I did read a lot about cracked screens and scratched cases. I may eventually buy a protective case but I don't know if I want change the aesthetics of the Apple Watch because even though it's a big investment I want to experience it how it's intended to be used. I think some people will have more use for it such as swimmers but it is something that almost anyone can use if you own an iPhone. I will most likely purchase the 38mm for my Fiancé but I'll wait a few months to see if Apple have an upgrade. I'm very happy so far with my purchase.
