Quiet, powerful motor. Easily sliced raw potatoes for scalloped potatoes and other vegetables such as cabbage for slaw, onions, etc. 
Lots of interlocks to preclude chopping off fingers, etc., but interlocks made it interesting/cumbersome to use the machine. I suppose after a period of use this will become easier.
Haven't tried it for making pie crust - this was a must-do task to properly assess its overall utility. 
Haven't tried it for chopping walnuts or other nuts.
Like anything of its complexity, cleaning is tedious but no necessarily difficult. It is moderately heavy and doesn't slide easily because of silicone feet. I have left it on the counter to avoid moving into and out of storage cabinetry. It requires lots of cabinet space/volume for its bulky attachments, but that was expected.
Overall, so far, it seems like a good multi-tasker purchase but time will reveal the true nature of it.
