Query: This slicer is a P.O.S.

I was very excited to use this product as my wife and I registered for it for our wedding. Needless to say it is a P.O.S.! Literately was shot after no more than 5 minutes of use. The tension wheel wore out. And even when it was working for 4 minutes, it cuts the slices at way too large of servings at it's thinnest setting.... Who eats cheese slices that large????
