I bought it to dice onions but you need to have strong hands to make it work. I tried tomatoes too .. what a mess. It splashed everywhere. Tried potatoes and I couldn't make it to work. Even my husband asked me to return it.

I found this product really hard for dicing onions and tomatoes -- the primary reason I bought it. You really have to press down hard to get it to works. So I ended up having to slicing the onions and then placing them multiple times into the chopper which was too much effort. The tomatoes ended up becoming mush. Clean up was difficult too as everything got stuck in the top part.

I've gone through two of these and finally given up on it since they keep breaking in the same spot along the hinge. I think the product is great in theory, it makes my veggies uniform in size, and I can throw soup together a lot quicker. My main issue with it is that it can be a pain in the rear to clean, even with the provided tool I still end up with veggies stuck in the lid. If the quality were to improve I would definitely purchase another one.

I've gone through a couple of these b/c I simply love the concept but unfortunately they are made poorly! While they feel heavy duty plastic and the blades do stay in the grate the PLASTIC knobs that hold the cover on and is used for leverage to push the onions through break off. Ugh its so dissapointing too b/c I simply hate chopping onions and this thing was a super time saver. I would tell everyone that until they tweak it and do something about those knobs (make em metal!!) then save your money!

Flimsy. Horrible customer service, I might add. I bought one for a restaurant I used to manage and, even though we only chopped veggies, it broke. I bought another one --- same thing. I emailed customer service and was told that the money back guarantee doesn't apply when used in a commercial setting. I find that to be sad. It's like they know their product will crap out on you. Pathetic.

I found this to be a bit of a pain to use. Having a weak wrist, it was difficult to press down. Sadly, mine cracked while chopping carrots only a week after getting it. Softer produce (like tomatoes) simply turned to mush and created a huge mess, and it didn't seem to go through the celery "strings" very well. It was, also, a hassle to clean the blades if juices happened to dry before washing.

I find it difficult to dice onions with the wizard because I can't press down as hard as necessary apparently. Agree with mother of 2 that you also can't do tomatoes...this product doesn't work well when your vegetable has a skin, it will dice the underneath, not the skin and it all sticks to the skin and doesn't chop all the way through. I will say this - it does make beautifil uniformed chopping, so it's great if you have to do a lot of chopping, espeically good for making veggie pizza as the softer vegetables like broccoli and cauliflower are a breeze with this chopper. For a dinner, its much easier just to chop with a knife and clean the knife, rather than going throught the hassle of this and doing the clean up, i never can get the onion skins out of the grates, even with the little tool it comes with. So I'm mixed about this...just depends on the job... I don't use it much.

A friend of mine made some fresh salsa which she brought to work. She was telling us about this new gadget she used to dice all of the onions and tomatoes with. The next dat she brought me a Chop Wizard as an early Birthday gift, and told me this is the gadget she used for her salsa. I couldn't wait to get home and try it out myself! I bought all of ingredients to make my own version of her salsa. I sliced the onion in half like it shows on the picture and pressed the top down. The onion got stuck! I pressed and pressed, that onion wanst budging! So I took my knife out and sliced across the top of the chopper to get the excess onion out. Then when I pushed the top down it went through. So i guess you are supposed to slice the onions into thinner more manageable peices. But doesnt this defeat the whole purpose? I tried using the dicing blade plate for the tomatoes but they got smooshed and stuck in the squares. By the time I picked all of the peices out of the blades and the amount of time it took me to clean up the mess it made, I culd have chopped them in my mini chopper. Sorry, I just wasn't impressed.

This is a good tool for chopping fruits, too (peaches, mango, apples). I use it to make tiny little squares of different fruits for a Fruit Salsa that i make with Cinnamon pita chips. I do have to admit, it is hard to push down on. I end up putting it on my kitchen floor and using all of my weight to press down. Still, though, it beats cutting all of my fruit into tiny pieces by hand!! I did buy one for my mom and my sister.

I have not used this product but i think it was be an asset in the kitchen. Cutting fresh onons is a chore and this seems esy to use and great to have around.

I bought this a few years ago and it worked great. But when I was using an especially tough onion the lid broke. I figured it was my fault and I bought another one. The second one broke as well. I think its a design flaw and it might have improved in the last year. It did work great when I used it and it made chopping onions really easy.

I have this product and have used it before. It is great for rough chopping onions. It doesn't make "french fries" like they say but It does dice potatoes for mashed potatoes, at least from my use anyway. I would recommend this to others that have alot of onions to chop up or have trouble chopping vegetables.

I own this product. While the concept is great, and it does work, it isn't as easy as it makes it out to be. You need to use great pressure to get the onion completely through. Also, the parts aren't made very well, part of the cover broke off the third time I used it.

This is a pretty neat slicer. I personally like my bullet so chop

With my daughter showing her first real signs of interest in cooking, I bought this in order to help her get past the dislike of chopping onions. If you cut the pieces small enough, it does take away the excess exposure, which starts the tears. However, with softer foods (tomatoes, hard-boiled-eggs, etc.), it doesn't do much more than mash the food. I do like the storage feature for any extra onions! In conclusion, it does help my daughter with onions, but not much use for anything else.
