Very poor build quality. My top oven door came off in my husbands hand first time he tried to open it, just after the installers had left. The door actually wasn't fastened together properly, the outside metal layer came off, the glass inside wasn't attached, and the inner metal piece was loose too, so the whole door came completely to pieces. Can't believe that this cooker got through any quality controls. Very disappointed as I thought Rangemaster was supposed to be a good brand, but I've used cheaper cookers with better build quality than this (and being a food journalist for over 25 years I've used a lot of different brands of cookers)
