It is for me. I am quite conscientious and I expect others to do their jobs at least as per the prescription, if not scrupulously. "New" means "new" to me, no exceptions.

As a matter of fact, I would go to great lengths in order to return or replace the coffee scale if that happened to me. It places my mind at peace to have things exactly as I expect them to be.

Fair enough. I'm quite happy to take the used product if it's flawless, in my mind that's a bit less waste produced by my lifestyle.

I’ve just kept a couple things, yeah; but usually I could have gotten a better deal if I purposely bought used or “renewed”, so the return is more about the price than the principle. For some things, I’d return anyway because the practice feels scammy and user-hostile.
