M3 Ultra with 256 or 512 GB RAM from China on eBay...concerns?

[rb2112]

hi all, I am considering getting a M3 Ultra Mac Studio with high RAM for local LLM. Saw listings on eBay with origin: China. Are these able to be protected with AppleCare? Concerned about support for non-US models. Thanks.

And sellers with zero feedback. Prices too good to be true. Use caution. Apple knows which serial numbers are in the US. These grey market products would not be covered. They maybe some cheap clone, like the iPhone clones.
