I liked the 12-12 so much I got the 12-18 so I could cut more strips without readjusting. They are great. The first slot shows wear but has held up great. I can't cut a straight line, so the JTSC was a life saver. I hang to store but usually it just lays on my cutting mat because it's my go to ruler. The videos are helpful. It can be used for cutting shapes per the video, but I'm a "stripper" lol most of the time and haven't used it for HSTs or other shapes. Best thing is to find what works for you. Joann's is have half off and free shipping over the holidays which makes the price better. I think amazon had good prices too.
