I love Mary Ellen's Best Press. I brought my first bottle home and removed the price tag so my husband wouldn't see it. After about a week or so he asked me where I had got it, and if it was readily available. He irons all his own cothes and absolutely loves it, too. He finally did ask about the price. I gave him the 50% off Joann price, and now he lets me know when "we" are running low so I can pick up more.
I use it on all my fabrics prior to cutting. I think it does a great job. And I love that it has no flakes when you do use it.
