I wanted to find self adhesive sheets in a store to buy because I needed them fast (I found there are a lot online, not in stores), and I found this product to be great! I was leery that the roll type product versus the individual sheets might be difficult to use - I had 8 1/2 X 11 sheets to laminate that I wanted to cut into thirds after I was done. I am so glad I read the previous poor review because I too didn't understand the instructions on the packaging and if I had not gone on You tube to WATCH how to use the product correctly, I would have most likely given this product the same poor review. Once I got the hang of laminating which happened after one time that I screwed up, the product was very easy to use and laminated perfectly. I was also very pleased after laminating the full sheet that I was able to then cut the sheets into thirds, and the lamination held perfectly on each card I made! I had wanted to make these laminated cards printed on one side and a blank area on the back so they could be used with dry-erase markers to write on. They worked great with the markers, easy to wipe off, and held up well ! The only thing that didn't work for me is the "repositionable" part, the first sheet I laminated that I didn't place properly, I tried to reposition the sheet on the laminating sheet and my sheet stuck and ripped to the lamination, so I found that part to not work. So after this long review, the bottom line for me is this product worked very well, I bought an extra roll just to have on hand for when I need it!
