Just a quick update to say I sent it back! One of the pins broke on the first use

Now I am more organised and by peeling and halving all the onions in one go, then putting slits in them all, then finally chopping them.

With the carrots I now wash them all (bag at a time) then top n tail them all, then slice them all. Bit like a factory line - but works cos it's a lot quicker

You will be chopping like a pro in no time!
