Since its such a great utility in kitchen saving so much time and space, and so easy to clean too, I thought I should write a review ... and by the way this is my first... this goes to say how happy I am. Also I heard from my friend that the one from the infomercial broke within the first one month... whereas mine is still going steady... :)
I bought this after testing out a similar thing at my fathers house. It makes salsa really easy and I've used it to make way more than any single human should consume at one time. Some onion, tomato, cillantro, lime juice, and garlic and you've got a great low calorie snack (except for the tortilla chips). At first I didn't use the other features (grader, slicer) but then used it out of curiosity and enjoy that too for making shredded cheese.
I actually bought it for my 33yr old husband that loves to cook. He loves to make salsa, slice tomatoes, onions, make omelets, etc. Honestly is a lot less pricey than a food processor.
After setting it up for her and doing a batch or two of potatoes I just couldn't resist, so I opened up the UltraChef and first of all, was impressed by all the attachments that came with it.I then uncovered the blades, installed them, and brought it into the kitchen and did a batch of potatoes.
We bought our first one at a flea market and my wife loved it so much that we ordered 4 more thru Amazon. One for each of our three children and a spare for my wife. My wife loves to cook and uses the Salsa Maker at least three to four times a week.
I love this product. I did find that it is very easy to break. I broke the handle on the first one and put the second one in the dishwasher and it warped the bowl. However, I still keep reordering since it chops so well. Better than my food processor.
It worked very well first 8-9 days. After that its performance degraded drastically. This could be just blade loosing sharpness. However,I wasn't expecting it to loose its sharpness so fast. Its still working, however, you have to put more power in it to chop anything. I use it 4 times in a week.Additionally, like others mentioned, handle does appear to be a week point.
I first saw a similar product at my friend's place who had ordered it as part of an informercial. So I got to searching on Amazon and found various products of similar kind from different brands. After reading reviews I just went with my gut feeling and got this amazing cutter. It makes it so easy for any kind of cutting.. vegetables and sometimes even cooked chicken which works great for my enchiladas....
I purchased this item couple of months ago but didn't use it for the first month or so. One day i opened the box and started using it. Within couple of days, i noticed rust on one blade, i tried to clean somehow but after a week or so all three blades got rust on it. I was about to throw it in trash and then checked with Amazon and they are courteous enough to accept my return shipment for refund as it is a defective box.
Answer: You'd need to slice your vegetable into manageable sections first, e.g an onion into quarters before you can dice it.
