"Under Irish consumer law, consumers are entitled to a free of charge repair or replacement, discount or refund by the seller, of defective goods or goods which do not conform with the contract of sale. These rights expire six years from delivery of the goods." [1]
My other negative experience was when my iPhone 5 was covered under recalls for the battery [2] and sleep/wake button [3], but Apple refused to fix it without a full screen replacement, for a "crack" so small I hadn't even noticed before sending it in for repair. It became a party piece of mine to challenge people to find the crack.
