Bests & Worsts Reviews from Amazon

I loved this when it arrived, it really cuts great and in a straight line. For the price I was super happy. Then I realized why I couldn't get my cards to look right... the measurements on the arm part of the ruler are off. I attached a picture: everything is fine until you get to the part that extends, then it's off by about 1/8 inch. Wouldn't be a big deal if you don't need that but unfortunately I do so I'm returning this.
