Got these to use with my recently purchased laminator, and they work great! A very large package for the money, these are sturdy and just the right thickness as advertised. You can use them in any laminator, as long as it is wide enough to except these pouches. Transparency of the items being laminate it was very good, and I have not had any issues with these wrinkling up or delaminating.

These are nice pouches, 3.5 mil so they remain pretty flexible. Had no problems running them. These are perfect for four-page (folded single sheet) jobs like menus. As soon as they come out of the machine and are still hot, quickly crease them in the center and hold the crease for a minuute or two and it will hold the crease. I like the rounded corners - saves me the extra step of trimming the pointed corners.

I have used a lot of different laminating sheets. As a preschool teacher I have been quite laminating happy. I usually use 3mil sheets; these being 3.5mil I didnt think would make much of a difference. However, these seem much thicker than what I usually use. I used the 3mil setting on my laminator and the sheets sealed perfectly. Also, the extra on the end stayed perfectly flat, no curling! Super impressed! My new favorite laminating sheets! Highly recommend!
