I wasn't sure at first whether this set was worth the money since I already have an electronic cutting system. However, hearts are a motif that I frequently use, and I liked the variety of sizes included. I am very happy that I purchased this die; I have already used it several times. The variety of sizes quickly gives me hearts that layer well, and at works just fine in my Cuttlebug.
I also like that the die is one piece, so with one cut I have lots of hearts to play with on my layout or card.
