Very satisfied this far. You are more or less forced to choose Apple Watch if you want a smart watch in combination with the iPhone. Previously had a Samsung Galaxy Watch, which worked great for Android, but turned into a semiconductor with iPhone. Now the functionality is back, with the change to Apple Watch, and it feels very feature rich. The battery life is clearly worse, but I can accept to charge every night, as long as it lasts all day. Notifications roll in as they should, the training functions, the heart rate clock and the ECG are clock (!) Clean and AoD of course you do not want to be without. The price is, as always with Apple, somewhat high, but as I said, you do not have much to choose, really. Interesting that it is possible to buy bands that cost twice as much as the watch itself, and also other materials on the unit itself, that the price can pull away high, high above 10k. Needless, however, as all clocks are identical on the inside, whether you choose aluminum or ceramic.
EDIT: After a few days the battery life has "set". Now gets two days off, with about 20 percent battery remaining. Then we talk 6-18 days with training, notices, calls, messages, music control and mobile payments. Of course with the AoD switch on. Good!
