I just got the hunter star ruler and have been having fun with it. Had I not watched the video, I think the instructions would be difficult to decipher and I'm quite good at figuring things out. Although you cut 2 WOF strips and squares, you end up with lots of bias edges so I really blasted my fabric with spray starch to eliminate as much stretching as possible. You also need to be very careful with pressing - press and not iron as it also distorts the fabrics. One great thing is, the blocks are oversized so you can trim before putting together which helps with the bias edge distortion. Overall, I am very happy I bought the ruler. A local quilt store carries her rulers, and they honor the paper JoAnn's coupons so I got it for half price!
