My one has a big fan oven (which is the one I use all the time), another big oven but this isn't a fan one and is not as good as the fan one and I only use this one if I've run out of room in the fan oven. There's an electric grill as well which isn't part of the oven. That means I can use the 2 ovens and the grill at the same time. There's also a warming drawer (but I just use this to store my trays!). It has 4 rings plus a wok ring and a warming plate area. I love my oven but my only gripe is that it has vent holes all along the back of the rings and I find food can fall through the holes if I'm not careful when stir-frying and once it's fallen through, there's no way of reaching the food. I think there should be a finer mesh to avoid food falling through.
I have a glass screen attached to the back of the oven (between the oven and cooker hood) and I'm so glad I decided to buy this because it prevents oil from splattering onto the wall and the glass wipes clean so easily.
