Let me start by saying I never leave reviews, I have been a member since 2008, and I am pretty sure this is only my second or third review out of hundreds of purchases. I don't write reviews if the item performs as expected. Quick and dirty review here: (more in depth review below for those who might wish more info) For dicing tomatoes, onions, and jalapenos this is a complete failure and a useless attachment, twice as much material gets hung up in the dicing grate or simply spins around the inside stuck under the blade, as what comes out the bottom nicely diced. I would give it zero stars if I could for dicing those specific items. I gave 3 stars because while I did not try it myself, I believe the dicing kit would probably work very well for potatoes and similar items that do not have a skin, do not have a fibrous plant structure, and are extremely firm, in addition as a food processor (for which I have no use) the attachment as a whole seems to be very well built, very heavy duty and up to the standards that kitchenaid users expect. More in depth review: I do not believe I am exaggerating when I say I probably could have achieved the same or probably better finished results (even looked the same) if I had stepped on the tomatoes, onions, and jalapenos to push them through the dicing grate. After every piece I put in the machine I would get about half out the bottom as a very nicely diced product and the rest was just mashed into a mat covering the top of the dicing grate (And yes I quadruple checked to make sure I had it put together correctly). To be fair to Kitchenaid they do include a device with the kit to push food through that is stuck in the dicing grate, I just do not think that after every single piece I put in the machine I should be required to take the machine apart to unclog it, and I don't mean every tomato, onion, etc. I mean every single piece of a tomato or onion, which was 1/4 to 1/2 of a medium roma tomato, medium red onions and average size jalapeno. This was the scenario with the tomatoes and onions. 1: Put item in top 2: Push item down with plunger if needed (usually not needed) 3: Turn off kitchenaid 4: Admire how nicely diced the 10-15 pieces that came out the bottom look 5: Remove lid 6: Remove blade 7: Remove the larger pieces that the blade was smearing around the inside and cut them up by hand. 8: Figure out where to line up the supplied tool to push clogged food through dicing grate as you cannot see the grate at all because of all the mashed mat covering the top of it. 9: Push unclogging tool through the dicing grate and rock it back and forth, side to side and up and down several times to dislodge as much matter as possible. 10: remove dicing grate 11: Rinse dicing grate in sink to remove all the skin and vegetable matter from the cutting blades that the supplied tool couldn't or wouldn't push through (which was usually a lot hanging up on the dicing grate blades) 12: Use the tip of a knife to pick out all the various larger pieces of matter hung up in the dicing grate that would not dislodge with the supplied tool or with rinsing. 13: Reassemble processor 14: repeat steps 1-13 for every single piece you put in the top If you skipped the above steps and went straight to a second piece in the top you get a few pieces fall out the bottom but as a bonus now you also get a bunch of juice and an added workout trying to push two layers of mashed vegetable matter through the dicing grate. If god forbid you tried a third or forth piece without cleaning the grate hoping in vain that these additions would push the previous layer through, you are WRONG you simply get tomato or onion juice and a mat covering the dicing grate that you cannot push through at all with the supplied unclogging tool. For those of you wondering, yes the roma tomatoes and onions were both very firm, not soft or mushy. I did try several alternate methods: 1: Blanched the tomatoes to remove the skins. No difference at all 2: Put and onion through behind the tomato to push the tomato through. Made a mess and didn't push tomato through. 3: partly froze tomatoes (maybe half as hard as a potato) to make them more firm. No difference 4: Froze tomatoes to almost as hard as a potato. very minor improvement 5: Froze tomato to as hard as a firm potato. Minor improvement but mostly just made the mashed up mess cold. A couple of hours in the freezer probably made dicing the onions about 50% better, mostly due to the fact that they appeared to shatter but still not what you would expect from an advertised "commercial style dicer". The Jalapeno was a total failure with almost nothing coming out the bottom, half being stuck in the dicer grate, and the other half as one large piece simply smearing around inside the machine stuck under the blade The food processor aspect of this item probably works as well or most likely better then most of the food processors out there given how powerful the Kitchenaids motor is and how heavy duty the attachment seems to be overall, but my experience is that the dicing kit is pretty much useless for the items I wanted to dice.
