I haven't used it yet but I bought some of the Warm Tater to try some with. Also on a video I saw it said to use the small bag for 1 or 2 potatoes & the larger for more. It said if you put just 1 potato in the larger bag that it could overheat & possibly burn. Also to wash the potatoes & don't dry them. Wrap in paper towel & place in bag. I have read evrything that I could find about them because I wanted them for Christmas & I will put all the directions with it. Hopefully the Warm Tater batting is the answer.
