I just used it yesterday for fries.  The fries were thicker so the regular fry button, 15 minutes, came out a little undone.  So I added 10 minutes manually and it was a little overdone.  I still have to fiddle around with this more to get the settings right.  Although I do recommend shaking or flipping halfway through. 
I wanted a big sized air fryer because of my family and indeed, it was a pretty big one.  I was pleasantly surprised to see the basket was bigger than expected.  Once I get familiar with the settings and such, I will give another rating.
