I was truly impressed with this processor. It is built to last. Not only does the bowl lock in place, but so does the lid. You can choose to push one of the preset buttons or one of the others. I recently made my first homemade coleslaw, wow this machine makes it so easy. Simply slip down some food into and turn it on. Make sure your blade is in the right way. The carrots and cabbage get so finely shredded. It was amazing. I like my coleslaw fine and no big hunks in it and I was not disappointed. This machine did better than I could ever have hoped for. I also love how to comes with the dough hook separately,  so you do not have to take any chances on cutting yourself. I am so glad to have this ninja food processor in my kitchen and look forward to many years of enjoyment.
