Bought it for mine. Have had to get 2 express replacements already in under a month! (Both manufacturing defects) Apple store would have replaced it, but it was going to take about a week for them to send it out to Apple and Apple to send them a replacement that I would have then had to go back to the store to pick up. So yeah, it is worth it to me for sure.
This is an unfortunate consequence of Apple's choosing not to stock white box replacements for the Watch (unlike other iDevices to date), and IMO this doesn't make for a very good customer experience whether or not you have AC+ (especially if your Watch is bricked).
I thought the price was reasonable and worth it just for the express replacement if needed. I NEVER buy these warranties but it does give some piece of mind, even if I never use it and it is looking like I might not have too as my SS42 has worked without flaw.
I am still trying to decide if I will buy one, but I probably will get the AC+ with it as I have read to many people complaining about scratches and such.
