We bought one of these to replace a 10 year old Zanussi microwave/grill. What was striking (in Dec 2012) was how appliances had gone downhill in quality (see reviews of previously well-regarded brands like Bosch/Siemens). AEG has a good reputation in appliances historically, but the built quality of this microwave did not bear it out. We also struggled to find a microwave with decent capacity like our old 30 L Zanussi. The standard sizes now seem to be 17 and 26L. Noticeably smaller and no good reason for this given that the overall space taken by the built-in appliance is the same. The AEG one just had legs to make up the volume. Unlike videos I found online of what seemed to be this microwave, the one we got did NOT have a stainless steel interior (painted white). In fact, the only difference between the white, black and stainless models is a frame on the front (and the colour of buttons). Its boggo standard microwave otherwise. The rotary knob is reasonably solid and feels OK in use, but this and all buttons are platic (nothing worse than plastic trying in vain to look like metal). As it happened, ours arrived damaged (cheap plastic frame being vulnerable in transit) so we sent it back. We purchased an IKEA model instead (Nutid MW6) which although a bit more money (£400 vs £350) is chalk and cheese in terms of quality. Its also 31L, 1000W and comes with a 5 year guarantee. Altenatively check out Which? for a handful of other built-in options which they recommend.
