I heard a lot of old quilters say they don't like this, sure glad I'm new at quilting, I love it.  Injuries to my back make it very painful to stand and cut the material for a quilt. because I'm new it seems to take me forever to make sure I have everything perfect.  With this it's trim the end and the next thing I know it's done.  I know it would have taken me so much longer because of my back.  You can watch videos on how to use this on you tube, very helpful, I watched them before I decided to buy this.  I am super happy  did.
