I don't use the bias tape makers anymore. I simply fold over the bias binding fabric and press. Then I sew the raw edges to the back and bring the binding over to the front and sew with a decorative stitch. It is faster and easier. I don't show my quilts so this works for me, vs. sewing on the front, folding over and hand stitching the binding down.
This is the binding ruler:
