Thank you for viewing. This is a 2012 model oven, and it heats and bakes without any problems. The flat table is quite dirty. (I often baked, so it never got clean no matter how many times I washed it... You might want to purchase a cleaner one elsewhere...) I'm wiping it down now, but I will wipe it down again carefully before shipping. ★ There are individual differences in the assessment of usage and deterioration, so please understand that this is a used item.
