Leaves part of the onion or whatever I'm chopping in large pieces no matter how long I push down on the top. Also, I have to push down so many times, it wears out my hand.
This chopper makes quick work of what used to take a lot longer. Uniform cutting and sharp blades that rotate. Easy to clean and store. We've used it a dozen times in the few weeks we've had it.
Had to return it. Tried chopping fresh basil, onion, and Roma tomatoes. Blade failed miserably. Tried garlic and was happy with the result. Not worth the process.
