I've used a different type of cutter with an interchangible "cartridge" style blade; it was wobbly and I could never cut a straight line! Because of that, I was nervous about this trimmer, but I wanted to try the magnetic system. I love it! It cuts like a DREAM! I can't believe I wasted so much precious scrapping time (and paper!) on that other cutter! This really works.
I was using a small portable trimmer before I got this, and was very limited as to what I could do with it, this trimmer is awesome, no more being stuck with cutting only what I could fit in the small one!
I was so looking forward to try the ATT, but I´m disapointed. The magnet is not powerful enough to keep the ruler in place while using it, making it slide on the paper. I find it to difficult to do the twist movement on the blade while pushing it down and holding the ruler in place.
I do hope they make one with a better magnet though, because its a great idea!!
