I can't stand the Kansas City Steak OAP, but I believe I already covered my issues with him in a much earlier post.
After watching the Ninja ice cream thig-a-mah-jig yesterday, I can see how MBR had issues with it. IMO, it looked very cumbersome. Plus when you wanted to add something to the base, you had to dig a hole in the center of the ice cream, etc. I'll have to read the reviews on it.
