Simple but effective. It's cheap, so do not expect bell and whistles but it suits me fine. Easy to install, although it only come with one shelf, so keep one from your old oven. Heats well - same cooking time as my old oven - and the dials are are simplistic; literally on/off, defrost, grill/oven, temperature. Used it about 10 times now and I still get a slight burning smell as it is new, but soon goes off.
