Query: Not very happy!!

I was very disappointed in these wires!! There was no choice on any of the sites for a size~~all were listed as 4" so I thought that was correct. However, when I got the order, the wires did not fit my slicer and were impossible to attach. The instructions showed several models of cheese slicers, but none were like mine!! The product only cost 3.95, but the shipping was $5.95 so not a good buy at all!!
