Brilliant design and fantastic performance. The HB43NB520B looks really stylish in stainless steel and glass, and it comes with plenty of features too. The main 50 litre oven uses 3D hot air technology to make sure you get a really even heat. It's great if you're cooking a lot of the same thing at once. The second 35 litre oven is conventional, so will always be hotter at the top and is perfect for browning food like lasagne. It'll be really easy to clean too as both ovens have ecoClean liners on the back, roof and sides. These absorb the grease produced when you're cooking and burns it away at high temperatures.
