I have all GE appliances so I bought the Air Fryer to "match". It's a nice size and I wanted something simple to use. The timer knob is the only thing I'm a bit disapppointed in because it's hard to tell if you setting the time to minutes between 10, 15, 20 etc... (For instance if you are heating something for 3 minutes it's hard to tell if you're on 2, 3 or 4 minutes as the lines are real close together.) The timer knob does turn off but maybe because it's new it is a bit stiff/hard to turn off.  I wish it had an LED timer knob! Otherwise so far we are very pleased with this product.
