All went wrong when I purchased a Neff double oven U2ACM7HHOB/55. It was recommended by Which magazine so I can't imagine what their "Don't Buy" ovens were like. Absolute and utter waste of money, cooks unevenly, takes ages to cook anything, dries out cakes, oven always looks dirty despite the pyroclean feature. The air vents are in the bottom of the oven door so grease gets between the glass door and can't be cleaned without taking it all apart. - poor design. Remove the door to clean it as per the instruction book and the hinges break and can't be mended and looking at their website that's going to set me back £130 to replace them. Save your money and buy anything other than one of these ovens. I'd try and recoup my money by selling on Gumtree or Ebay but would be too embarassed to pass this on to anyone other than the dustman.
