The door opens fully. The face plate doesn't fit under the worktop, but it doesn't look weird at all.
Really, I'm only worried the heat might crack the tiles because there's no gap?
We have accidentally bought a built in electric double oven, but it fits almost perfectly under the worktop, opens fine and is a great size.
Is it safe to not have loads of space around? There is a big gap either side, just not above or below.
