Oh dear I must be alone in this! The pingi bag turned pink which means it need to go in the microwave, I put it in for 4 mins and it came out with the penguin pic nearly completely gone and the ink all smudged. Left it in the car last night and it didn't work the inside was wet and icy again, think I have broken it! Beware all it says 4 mins on 650watt oven who has one that low mine in 900watt! oops have to buy another one now!
