I have had a 42mm Series 2 stainless for about 8 months. iMessage and music control on the watch is excellent. Dictation for texts works great. Siri still sucks diks. Remote camera control is cool. The Apple fitness app integrates with MyFitnessPal beautifully and the health aspects are great. Battery life for me is decent...better if you don’t exercise as much. Calls through the speakerphone works pretty good, but volume is limited. I didn’t think it would be worth it, but notifications on the wrist is nicer than I thought. The 3rd party apps are pretty much garbage tho. Wish it had an Always On Display like my friend’s Samsung Gear...that’s a nice feature.
