When does seller's responsibility end?


I'm sure this has been discussed before, but a search could not find it.
I sold a Naim DAC (mentioning this because Naim is notoriously reliable) to someone on November 26, shipped on November 27, 2012.
Did not hear anything one way or another until December 19, when seller emailed to say one USB input would not work with his ipod. Well the input worked for me when I had it. I asked him to be sure he was doing everything correctly, including checking for bad cable. I am not sure the input really does not work.
No word again until December 25, when he asked if I would pay for repair. I answered no, because I felt the time period had been too long and my responsibility was over.
Now he has initiated a dispute/claim against me on Paypal. They have put my account in the negative for the amount of DAC until they resolve it.
Sorry for the long post, I just wonder if there is a consensus on how long a seller should be responsible for "sold" gear. I say a week, maximum.
What say ye?

This might be an individual decision, after a month, I would take care of my customer and pay for repairs. A situation similar to yours happened to me several years ago. I ended up loosing a few hundred dollars but suffered no heart ache and the buyer was very happy.
To validate the buyer's argument, why not ask the buyer to send you his Ipod so you can check it out for yourself... ... ... fair is fair.
I would take the DAC back, with the buyer paying the return shipping, and refund his payment less any costs incurred for ebay and paypal.

You can resell it. I would indicate no returns in my next ad.
IMO as soon as item is delivered and confirmed to be in working order. I would say 24-48 hours or so after delivered.

Thanks to all.
Sgordon1 that is exactly the problem. Nothing has been diagnosed, nor has any cost of repair been put forth. It is all based on his word to Paypal.
I believe if the USB isn't working it is due to user error.

Too early to know or worry what PayPal will do.

I hope you saved all your emails between you and the buyer from day one to the present. Day one being the first time the buyer first inquired about buying the DAC from you.

I suggest you send a copy of all emails along with the original ad you ran for the DAC to Paypal.

Also in your reply to PayPal state when you shipped out the DAC the unit worked fine.

If I were you I would say you nor PayPal have any proof that there is a problem with the DAC..... The problem could be user error....

The only sure way to find out if there is a problem with the DAC is for the buyer to have the DAC checked out by a qualified service tech.
(From my limited experience with PayPal the buyer eats the shipping cost, if any.)

More than likely PayPal will agree and require the buyer to have the DAC checked out.

PayPal will more than likely require the buyer to provide proof the buyer has the DAC checked out by a qualified service Tech. They will not just take the buyer's word. The buyer will have to provide documentation with an official business typed letterhead.

When corresponding with PayPal choose your words carefully.
You will catch more flies with honey than with vinigar.

Good luck.
