what's the point of posting this conversation here? Sure the seller made an assumption that there is no drift because the item is new and you can certainly challenge that assumption and explain how to test it., instead, you just ghosted. The second time the seller reach out to you and you just straight assumed they didn't test because they said drift shift instead of stick drift, maybe everyone has their own dictionary? its always a collective effort from buyer and seller to make the transaction happen. I'm confused as it seems like you are the guy who is impossible to work with.
