Not really versatile!

I have the "Fresh Express" buy to quickly chop cucumbers or onions. The problem is that I need the vegetables already so much pre-crushing in advance so that it even fits into the upper opening!
This "pre-crushing" is not particularly worth barely use the device, because a lot of pressure on the vegetables must be exercised so that a contact with the sounds produced. My cucumber / onion has lost a lot of fluid and overall was the result rather insufficient.
Too Bad. Classic bad investment.
