I pay for AppleCare+ for my iPad Air and my Apple Watch on a monthly basis. Like all insurance, it’s worth it only if you ever need it. Chris Rock once made a joke saying that they should call insurance “in case shit” because it’s only good in case shit happens. The only Apple product I’ve needed to use AC+ on was my Series 3. I ended up getting a new/refurbished watch, no damage and new battery. That was in June of 2020, 2 years after getting my watch. And then I traded in the Series 3 last year for a Series 6 and got a full value trade-in. Which I obviously wouldn’t have gotten if I didn’t have a working watch to trade in.
