After 10 years it's finally packed up. Depsite my buying a fridge thermometer yesterday, and despite it showing 'warm' even on it's highest setting, and despite H saying 'Are you sure that thermometer's working' and me putting it in the other one just to prove it is, I need to get a new one. After I've convinced H it really isn't working.
But I need to start looking now - anyone bought one recently they're really happy with?
