Great product
Whereas the product is wonderful, the non-sharp (no blade) cutter is extremely difficult to install.  The graphics on the box are near-to-impossible to understand.  I ended up calling the company for help.  The woman I spoke with was very kind and helpful.  40 minutes later (1) we figured it out.  The woman told me that her boss had a lot of trouble, as I did.
