Buyer complaining item is faulty over 30 days after receiving?

[noctilucence]

Buyer messaged me complaining that item is faulty 32 days after signed delivery date. Not sure whether or not to respond...and if yes, what with? Can they open a case against me? I already know how eBay is, and that they would side with the buyer. (Very rare that they don't...) I've also heard they can open a PayPal case after 180 days??

I'm a small seller and as of recently I've incurred a fair few losses due to buyers claiming item not recieved and I just refund or replace with no hassle. This is a more expensive item I am reluctant to take a loss on...or I'd be breaking even at this point.

Thanks in advance.

Edited to add: Item was a used item.

They  are just about out  of time for an ebay case. They can open a dispute but they can't escalate it.

Yes they can open a Paypal dispute but Paypal may see it as a warranty issue which they won't hold with.

There is no saying really.

"They can open a dispute but they can't escalate it." not sure what this means...

It just means they can go through the motions of opening a case but it won't go anywhere. It will time out in the seller's favour.
