Love the slots .The split muffins and bagels don't stick.  The defrost setting is a nice feature. It is recommended to use it before toasting and it goes straight into the toasting automatically.  The digital numbers takes the guess work out. I know that the whole grain breads take a level 5 and white bread less. The only defect I have found is the toasting is uneven on the 2 sides. One side of the bread is less toasted than the other. And it is the same whether you are using the right side or left side or all slots.
