I like the Binding Eaze because the iron can be left on the silicone mat at highest setting with no worry. I can zip through a binding for a king size quilt in a couple of minutes. I can have the binding feed through a bias maker before the iron if I want single fold bias. I have the original Simplicity Binding machine and I use it a lot too. It folds and presses with a push of button. I have the 2 1/2 inch binding tool for it to make double fold straight binding as well as different sizes of bias or straight binding. My granddaughter use to make binding by the yards using the machine and selling it to guild members. She paid for her pool membership each summer doing that.
