Ordered a heat changing photo mug for Christmas that was supposed to be delivered on the 21st, the mug didn't arrive until after New year. Several emails to customer services and they just refunded the postage. Upon giving the gift they opened it to find the mug was transparent and the black coating wasn't hiding the image. It was supposed to be a surprise but was ruined by the fact it was clearly visible without any how water in it. Customer services said, its a novelty item so can't expect it to be as good as the advert all the time. We have had these before with no issues.
