Summary: I do like a lot of the features. I can keep track of emails and texts easy as well as letting you know who is calling. You can also decline a call and let the other person know you are busy. I also set mine up for Facebook and twitter updates. The next watch probably has a camera and able to talk into, as those are options that are there but the watch is not capable of doing. I definitely love that it is water resistant.
Summary: My SW2 seems to be put together very well. My phone is an HTC One with NFC so connecting is a doddle. With the phone unlocked I touch the back of the watch (which is not switched on) and it powers up instantly and is up and running before I can put it on my wrist. First time your phone will tell you what to do and it is all very simple.
