I have the white Suprene Slider and I have mixed emotions about it. It does not fit well on my free-arm extension table and being loathe to cut it, I taped it down under the extension table where I could. I think it helped with moving the quilt, but it seemed to be a constant irritation to me all the while too. I think if your machine is in a recessed position and not with an acrylic extension table butted up to it, it probably would work a whole lot better.
