I bought this because I'm always using my small one (1.5 cup)  that is 15 yrs old for Onions. I figured a bigger one, I can get more done and get it done quicker. Well, that really isn't the case. It doesn't really  chop. It only purees the onion that is at the bottom. I had to take out the unchopped onion that was on top, pour out the pureed onions and put more onion back in. Then only turn it on for a bit, so it woulnd't puree what was as the bottom.  It ended up taking longer than my little chopper. I find my 1.5 cup much easier to use. Thankfully I didn't toss it when this came in. I will figure out something to use this for. Just don't know what yet. So, I would not recommend this to anyone, unless you want to puree stuff. 

Pros: Great value, fits more food, nice look (the black one)
Cons: it purees more than chops
