great for on-the-go crafting
I added this rotary trimmer to my shopping cart because it was on sale or clearance, I don't remember. I have been using it, the 3 blades are ok but not the best of the market. the trimmer is lightweight, that could be a good thing if you are travelling but not so much if you want something sturdier that cuts your paper like butter. I won't use it for large papers, it's difficult to align the paper with the ruler on top. I like it for small pieces of paper, for standar size cards and such.
for me, it's a plus that it comes with the rulers in inches and centimeters.
