We've had this blender for 3 or 4 years, and use it more than we did prior blenders. The large capacity blending container is great (but we also have a smaller capacity container with the dry blade). Dry blade is handy for spices, salt, even making fresh flour.
Cleaning this unit is a snap. Just put soapy water in the container and blend for a minute and rinse out. No disassembly required.
