Hello Kirkiegirl,
Welcome to the madhouse!
I think the bowl part will go on forever, must be the electrics that pack up.
Apart from the unsuccessful yorkshires I tried the jacket spuds have been fine.
Still rather daunted at trying anything new in the oven, the lack of any real directions or recipes I've very annoyed about.
I bought mine from Coopers of Stortford, won't be buying anything else from them.
