Just bought the Indesit Aria double oven for a built in unit, this was to replace an existing under worktop gas oven, I installed a new tower unit and booked my local electrician to relocate the wiring and connect the oven, the whole job took no more than an hour and my wife is really pleased, the Aria is a very nice cooker to work with and looks good, it has some excellent features and even I can use it, I like to eye level grill and the smaller top oven means that you can cook meals for one or two people without heating the larger oven, so energy saving.
Plus my wife really likes the larger oven that has a light when cooking so you can always see how the dish is doing.
We reviewed at least 10 to 15 other makes and models and this one came out as the best for us, when you considered all the features, like size, oven capacity, dials, buttons and displays plus general appearance.
One negative feature is that it has only one shelf per oven, just one more would be helpful.
