This cutter is a work horse. It does a great job cutting both very thin and thick stock. I've used it to cut up to 8 standard sheets of paper at one time. Above 8, the cut edge is a little jagged. But even after thousands of cuts, it is still sharp enough to cut even the thinnest single sheet of paper.
It met my expectations, and is a very useful piece of equipment.
The unit performs beautifully. The packaging could be better as I had to take it apart to fix it as the blade skipped onto the plastic rail. Also, the rubber on the cutting handle doesn't want to stay on and I had to use contact cement to nail it down. After that, it works as described. Squareness has been a problem with all the cutters I have used. You still have to eyeball it to get the precise results. If you do use the guides, you will get close enough for framing and album insertions.
Overall, this unit has trimmed everyday paper to cardboard and it still cuts like new after all the use and abuse.
