I've only used it a couple of times so far. It's twice the size as what we had before, that's why I bought it.  I didn't use their setting the first time I made store-bought frozen fries, and regretted it...  I increased the time and temperature to match what was on the bag, and I burned them.  Lesson learned!  I did make some homemade fries, though, and they were perfect using the default fries setting.  I found that the instructions are poorly written and filled with typographical and grammatical errors.  I contacted Support and they allowed me to edit their manual for them.  :)
