Simple to use. I have found that cooking meats on medium instead of the recommended hi setting ensures a proper outcome. Cooking on high seems to toughen meat. After using the grill we simply immerse the unit in some water while it is still hot. Then we clean the unit with the brush and it does take some effort with hamburger especially. I have wondered if this is just an air fryer with different temp settings that allow grilling because I don’t see an actual difference in cooking methods.
