We have used it a couple of times so far.  Since we had already has a regular air fryer we were able to easily compare the two.  We tried breaded chicken strips the first time and I will have to say they came out great!  These were so much more juicy than what was experienced in our old air fryer.  Tonight we tried a frozen pizza. We usually use a pizza stone.  It cooked really well.  I do think we took it out just a little early.  But overall it cooked it very well.  
We really can’t wait to use it as a dehydrator!  I would recommend this to anyone who wants an all in one appliance.
