The appliance rule of thumb seems to be that the more abilities a machine has, the more complicated its usage. This air fryer / toaster breaks the mold on that one! All the buttons are clearly marked and straightforward, and there's even little safety additions, like a plastic shield between the handle and glass door to protect from accidental burns. I do wish the one tray was a little bigger, but that's a minor detail. Overall I love my new toaster!!
