What a cool machine! I bought this for a friend who is a teacher and she cannot depend on the office staff at her school to laminate projects for her. That fact is a whole other ball of crappy that has nothing to do with this machine.Originally she bought a Scotch Laminator for about $30 from Walmart, which works well, but ideally she wanted to use thicker laminating sheets and thicker paper card stock to extend the longevity of the items laminated. That Scotch machine works great! but, with the heavier paper and sheets it just doesnt quite make it. So, I bought this one for her. It is well made, heavy and appears to be a professional machine that I believe will give her years of service. She is super happy with it and has reported to me that it is super easy to operate, the sheets regardless of ml come out perfectly laminated. Thanks Fellows for producing a great machine, a teacher can rely upon to create projects, and educating tools for her second grade classroom.
