I have a supreme slider & at first I didn't like it at all. It didn't stay put & I sewed into it.I put it away for a long time. About 6 months ago I got it back out. I sprayed the back with temp. basting spray & now it stays put & I love it. I don't even have to tape it. When I change the bobbin I just roll one end out of the way & it rolls right back down after I change the bobbin. I am thinking about getting the bigger size now. It does leave residue on your machine bed but I don't mind that because I only use that machine for quilting & the mat is always on there so no problem. Also it does wash off if needed or if you want to remove the slider.
