I have an old one, and it has never been good. I am planning on getting a better one soon. It will have a less tapered container, one with squarer edges as well. I have decided that a wider bottom is better.
I have looked at the Ninja blender but, nobody I know owns one.
I'm feeling bearish, and I'm packing a Wusthof Grand Brisket slicer from MABA
