Always, can't pull out crumb tasty without spilling crumbs from one time if toasting w slices of bread. Also, it stained by the third time I used it and found I couldn't get stain off because a plastic scrubbie started to remove surface coating. Started to cook food that had oil on it, on high with fan, & it started to smoke! I will not use it as an air fried as a result.& won't be able to do broiling as I am used to.
