This watch was an upgrade from Series 7 and Its revolutionary. Love the recessed buttons from accidental pushing. Love the solidness and features. It has all the normal features but added a lot of outdoor features like hiking or exercising. Battery life is incredible.
Still have not fixed the problem. Watch does not connect to service

I heavily rely on the health app and the Apple Watch helps me to remember to take meds. I had the series 8 watch but it wouldn’t get past the day with this watch I get 2 days easy
The watch is great, but it did take approximately 5 to 7 business weeks to complete the updates to the iOS (sarcasm). The band is total garbage. Fortunately I ordered an aftermarket replacement and overall I’m really pleased.
