It wasn't me, but Kayleigh bought us a new microwave. The previous one, a Panasonic, wouldn't start half the time and would also stop cooking at any time so that we kept having to press Start again and again.
So now we have a Samsung microwave. Kayleigh measured it at the store so we knew the width of it would fit in the nook. It's just sticking out a bit, that's all. She didn't measure depth.
