This is nice that it combines many functions in one appliance. It is rather large and needs space to vent around it when on use. I was able to use on my counter and just have to move it forward when in use to allow room to vent. You can definitely hear the fan running when using the air fry mode. I am looking forward to trying many foods in the air fry as this is the function I was most interested in using. I do like to use it instead of heating up my full size oven when I can.
