The first couple of tries had bubbles. The trick is creating the correct amount of even pressure on each adjustment of the rollers. If it’s too tight it is a problem. I loosen it, put the items in the rollers, lower it down to where it just snugs, then give it 1/2 to 3/4 turn. Each side should have equal pressure. Play with adjustments on scrap until you get it right. When it’s adjusted correctly it works amazingly well.
