Good microwave- overly pricey

Very good Lots of features. Lovely looking- we hate being able to see into an oven so the black glass (until it cooks) is a great idea

Smeg Classic SF4309MX

Looks good and functions well. This is a SMEG product so good construction and mechanics. A quality product that should last for years to come.
