Love the fan oven, although it does hum whilst on, you wouldn't expect it to be quiet. The grill pan fits the shelving space but is a tight fit, I'm sure with use it will slide in easier. The cooker stands slightly taller than my worksurfaces, no problem with that, but if you were looking for seamless edges it may not conform. Love the big capacity, able to cook larger pans & with a 3rd shelf is copinig with a larger family needs well. Liking my cooker so far.
