I love my air fryer, love it! I use it everyday. I cook in it, reheat, toast bread & rolls. Seafood, chicken, sausages, sweet potato fries, garlic bread, etc. I slice tomatoes and they come out toasty and I place mozzarella cheese immediately on top. I don't own a grill, so on the 4th I put beef hotdogs in the air fryer and they were fantastic -- crisp skin and tender center. I come home from work and know I can cook from scratch and it's ready in minutes, or reheat food and the settings make it incredibly simple to time it when it's ready.
The crisper would mean I have to pre-heat my oven, and have it on during the hot/humid days.
