This 3 in 1 Microwave,Air Fryer and Convection oven from Galanz is huge. Be prepared to use a bit of counter space for this oven. It's also a bit heavy,at almost 50 pounds. So it can be a little hefty getting it in place. 

I like that it comes with big air fryer attachments and a turntable glass dish. Makes air frying and microwaving foods very easy. The knob does give it a retro feel to it.  Instruction booklet provided was very helpful on how to operate it. So far it's made cooking a breeze.  Very impressive product!
