<span style="font-family: verdana,geneva; font-size: medium;">Joe,</span>
<span style="font-family: verdana,geneva; font-size: medium;"> </span>
<span style="font-family: verdana,geneva; font-size: medium;">I bought the Ninja last fall, thinking that I would use it for Christmas cookie dough, and, of course, for blending and some food processing functions. It failed miserably at both the food processing and the cookie dough functions. </span>
<span style="font-family: verdana,geneva; font-size: medium;"> </span>
<span style="font-family: verdana,geneva; font-size: medium;">First, the processing: The blades are arranged such that they just miss some of the food at the bottom, and the shape of the bowl defeats the food circulating properly. I noticed after I bought mine that Shark redesigned the bowl so that it is rounder. The one I had was square. Perhaps that would make a difference. Anyway, it could not completely chop onions, carrots or zucchini. I was constantly having to open the top and clear the food from around the blades, which is not entirely possible given the shape of the bowl and the arrangement of the blades. </span>
<span style="font-family: verdana,geneva; font-size: medium;"> </span>
<span style="font-family: verdana,geneva; font-size: medium;">Dough processing: Even worse. Even in very small batches, dough becomes lodged under and around the blades. The machine constantly overheated because it could not move the dough, even though there was not much of it. Also, be aware that Shark only makes the bowl and attachments for dough processing using the SMALL bowl. The larger 72 oz. bowl cannot be used for dough mixing. Good thing, too. I would hate to have to keep removing that large honkin' blade assembly out of that large bowl every time it got clogged.</span>
<span style="font-family: verdana,geneva; font-size: medium;"> </span>
<span style="font-family: verdana,geneva; font-size: medium;">Blending: it did much better. I made several nice smoothies and similar concoctions, but this was not enough to redeem the machine. I took it back and got my $165 back. I was very disappointed. I bought a Hamilton Beach blender that I use for smoothies and other blender chores. Before next Christmas, I plan to buy a real food processor for some of those sorts of processing chores. </span>
<span style="font-family: verdana,geneva; font-size: medium;"> </span>
<span style="font-family: verdana,geneva; font-size: medium;">Though I think Shark is getting better in the vacuum cleaner arena, this machine was a big zero. I would have to say it was because of poor design and engineering. It just was not up to most of the tasks they brag that it can do.</span>
