Returned goods- only received half money back

A question about : Returned goods- only received half money back

Hi, i am looking for some help.
My husband ordered an in car stereo/amp system from a website. When it arrived he fitted in and tested it. The quality was terrible and he informed the company that he would like to return for a refund.
They emailed a prepaid postage label and the whole lot was returned. Most of the speakers were not in original packaging although he did inform them of this at the time and it was within 7 days of receipt.
Yesterday he received an email telling him he had been partially refunded, Ј79 back of an original purchase price of Ј150.
Is this fair? No other way to test the system other than fit it and the quality was awful. I feel he should have got more, if not all his money returned

Best answers:

• The new Consumer Contract Regulations state...
  "A deduction can be made if the value of the goods has been reduced as a result of you handling the goods more than was necessary."
  By not returning the full packaging (and perhaps it had been marked from the fitting/removing process) then the product can not be resold at full value so they are in their rights to withold some money. Although perhaps nearly half was a bit much.
  I should point out that the CCRs also state...
  "The extent to which a customer can handle the goods is the same as it would be if you were assessing them in a shop."
  Which wouldn't allow you to fit it (although a demo model would normally be available) and you would certainly not be able to keep any of the packaging.

• Thanks
  How else would you test incar speakers? They weren't returned as we didn't like them, we returned because the quality was terribl, they were not fit for purpose
• The quality of speakers is subjective, what's good to someone isn't good to someone else. What shot you in the foot though was not returning it in it's original packaging, returning it so early your husband should really have made the effort to package it the way he received it.
• Goods were not faulty, just of poor quality for the money.
  I still feel they have over charged excessively...had he kept them he would have got more for them on ebay than what they have refunded him.
  Thanks everyone for your help!
