It's probably not the right attitude, but as an international customer, small defects are simply too much aggravation to even consider shipping back for replacements. By the time packages arrive in the UK, DR have usually run out of CS stock anyway. Added to that Mattel decreed that an e-mailed photograph wasn't enough evidence of a fault and expected the item to be sent back.
So in principle I think that defective items should be replaced; in practice I think it's a futile pursuit. Maybe it's simpler for US customers.
