US Audiomart, apparently has no standard that is enforced...sales are "as is"; however, the ad indicated full functionality. Pay Pal is the likely enforcer, I guess. I've bought & sold a number of items on the internet, and this is the first problem I've had with a seller...I've had product issues before, but sellers are generally more than willing to get the issue resolved equitably.
Who is Liable with Defective Unit
Purchased a used (10 yrs. old) DAC on internet...was represented "as new", in perfect working order. Arrived OK, packed well, etc. Plugged in and unit would not respond to remote input. Works with manual input. Remote is OK...can see IR pulses with my phone camera. Sent to factory repair for analysis...PCB problem. Seller will only agree to pay 50% of purchase price if returned, which is also about 50% of the repair cost...claims unit was just fine when he sent it. Pay Pal transaction. What remedies do I realistically have?
