This is a replacement for an earlier version that lasted less than 3 years when the dial quit working and the heat would randomly shut off.  We didn't want to buy another but couldn't find one we liked as much and are hoping this one lasts longer! The size is perfect and the dual racks are very convenient for keeping food warm.  I cook regularly in this oven on a 12 inch pan that fits perfectly.  Works for everything from toast to leftovers...even works for baking.  I am hopefully we can keep this longer than the last one!
