I have one. Not sure if it's the version 1 or 2. It looks just like the video. I bought it to quickly cut up scraps and fat quarter material but haven't really used it much. It is heavy so moving it back & forth between it's storage spot and the cutting table is a chore. I still think it's useful, I just haven't taken the time to really "learn" it. I do know that it's got the most common angles built into it so no fussing with lines on a ruler if/when I get around to cutting up my scraps & fat quarters into hexes, triangles, kites, diamonds, etc.
If you cut a lot of these angled shapes out of smaller pieces of fabric, I think it is a great tool. I'm usually trying to get something done in a hurry using squares and long borders so a regular rotary ruler is all I need for that. One of these days I'll get to really play with all my toys--LOL!
