I finally got a chance to use this thing.  It is very easy to use. The only issue I had was pouring the batter into the bowl as the opening is a little small so I made a little mess. A few things recommended you do. 
1. Make sure your bowl is super cold. Crank your freezer down as low as it goes and leave it in there at least 24 hrs before you want to use it. 
2. Make sure your batter is also chilled enough before you pour it in. It will take longer and you will get some melt and it won’t cream completely if it’s not cold enough
3. I ended up using a recipe online but there is one in the manual and it uses eggs. They are all relatively the same recipe though
