Ashamed it’s not working because the size is actually what I wanted after about 2 months it would not shut of unless I left door open. That stopped  and just started again except now it won’t stop running again. So you put what you want to heat inside set time hit start it beeps when time I done however it doesn’t stop running so you open door it stops . But you have to leave door ajar or it will just run.
So sadly I have to get another.  I have to see if they’ll let me return it. Haven’t found out yet.
