BLACK+DECKER Black One-Touch Chopper

I bought this easy to use , excellent product and I am pleased with and recommend it to everybody.

We had an old Black and Decker chopper (must be over 25 years old because we got it from my mother who died in 1991) which died so we asked for a new one. When we first got this a year ago, my husband said it did not work. I checked and found that he had not gotten the lid on completely. It is really difficult to get the lid on completely. I broke my right wrist in June and my husband had to do all the chopping until I got use of my right hand back. Last week I was trying to get the lid on when it broke by the locking mechanism. I see that a lot of other people have complained of the same thing so I am not alone. As we have had it less than two years I see it should still be under warranty. Though, if the price were right, I would be willing to pay for the new lid. I just need help with getting this done.
