We got this thinking we would be standing it up every time we used it. Turns out for us, it’s less cumbersome staying down as it short hight make it appear smaller than it is.
As far as function goes, it’s very simple to use.  You literally pic a function set time and temp and your done. It heats up incredibly fast.  Your at 450 in a minute or less.   It def takes some getting used to as far as how to cook what.  If anything I’ve noticed it cooks a little faster than you would think.  The book recommendations are for some larger portions than you may be using so you def have to monitor it until you get used to it. 

It’s also really easy to clean. If I had to complain about anything..... it would be nice to have an open cook or toast function just so you could turn it on and go.  But it’s not that big of a deal.  It’s def narrow height wise,  but I think that’s obvious before buying. 
Enjoy!!
