The discs might have been fine, we don't know. REAL problems with the delivery company..City Link. Out when they tried to deliver the first day. In ALL DAY the next day,in lounge, right by front door, heard no knock or bell ring, BUT did hear the sorry you were out card being put through the letter box. Thought it was the postman as it was the right time, by the time I got to the door and found the card, person had gone. They charge for 3rd delivery, you can't speak to a human easily when you ring them. Gave up and chose the send it back option!! IF IT'S GOING TO BE DELIVERED BY CITY LINK, DON'T BUY IT !!!
