Because it has a plug it was easy to fit myself without having to pay for an electrician; needed a hand from another person just to fit it into the space vacated by the old oven, but after that it was simple to follow the installation instructions. Make sure you "burn off" the insides (run the oven for an hour without actually cooking anything) as there is initially a strong smell which may contaminate food. Apparently this is normal with new ovens. Very useful range of features, but not overly complicated (Do you really need an oven you can switch on using your phone?) with less things that can go wrong, i.e software. Still getting used to it, but very happy so far.
