When I first got this dryer I was confused on the settings because I would set it for a cycle but it would stop before it was finished.  I realized I had the AI learning setting on and it was ending it at the recommended AI time.    It hasn’t had enough time to learn the cycles I use so I turned it off for now.  So in case you have the same issue you know how to resolve it.  Other than that I love the dryer.   It does dry fast and it has so many different dryer settings to choose from.  Once I have used it for some time and it’s had time to learn my usage I will turn on the AI setting   again.   The thing I love the most is the lint tray is enclosed.  So when you pull it out all of the line is contained inside the lint compartment.   You have to open it up to remove the lint.  This makes it so easy to clean the lint and keeps it contained.
