I have one of these, the type with two fold out wings. It is working (heats up) but clothes don't dry fully on it. Well, only the part in direct contact with the heated bars does. I've reduced the amount I put on and spread it out. Tried a king sized sheet over the top as a makeshift cover too. Still no luck.
We do lots of washing - busy, sporty family - with a 10kg washing machine and I resort to using the tumble dryer more than I want to.
Should I just give up on the heated airer?
