I must say, I am a sucker for the "As seen on TV" aisle in Target and I bought the Vidalia Chop Wizard on the recomendation of a friend of mine. I have to say that I love it!
I can chop an onion and a bell pepper in less than 40 seconds and it is neat and clean and so easy. You do have to use a little muscle to push down on the lever, but I just put my weight into it and VOILA! Its all chopped.
I love mine. Here is the link https://www.chopwizard.com/?s_kwcid=vidalia%20onion%20chopper2130969259&gclid=COK4h7qC4ZwCFQKdnAodwzLLIg
In case you ever wondered if it reall works....it does! I really love to make stir fry and this has made it go so much faster.
