Query: Piece of Junk

It's advertised as being "The last one you will ever buy". They were right about this as I will not buy another one like it until there are some improvements.It runs too slow and after only a couple of uses got jammed with the can and I couldn't get the two separated.You guessed it - I had to throw everything out - can of food and opener because I was afraid I would get hurt trying to get the two apart.Waste of money.
