Review: Works on laminate! - I print and laminate all my recipe cards. Since I have to cut down the laminated part the corners can get quite pokey. This little corner rounder solves that! Purchased a cheaper one first and was very disappointed… get this if you need to cut laminate.
Review: Hold it flat and you're set! - This is a nice corner rounder that doesn't take off too much of the corner, but rather just rounds it off. Line up the paper with the guides, not the blade, so that it rounds just the corner without making a new one. Don't force the paper into the blade opening. If you hold the cutter upright it will catch the cut pieces, but turning it sideways can either make a mess on the table or jam the blade with scraps. It's easy to clean out, just make sure you line up the plastic bottom in all the holes. I got this to round off my business cards for a more organic shape without paying the extra money from my printer shop. I got through 1000 business cards, some bookmarks, and a ton of cardstock, and there's no sign of the blade dulling! Good quality.

### ⭐⭐⭐⭐ It jams a bit.
*by B***N on February 6, 2022*

I used it for a while now and there's moments where it jams and won't click down, eventually after using it for a couple of months. Just beware of it. Also don't use anything that's thicker than printer paper, it just won't do the job unless you want it to jam more and mess up what you've got.
