I have one and couldn't live without it. I do baby quilts for my son's friends when they have their first baby. I do a lot of applique, small and very detailed, and couldn't do it without it. I cut templates from heat-resistant mylar. After clipping the seam allowance, I use a small paintbrush (like from a kid's water color set, nothing fancy) and paint the seam allowances with liquid starch. Then I use the iron to fold over and iron the seam allowances. Makes very crisp lines for the applique. Boy, I've never had the problem of it not getting hot enough! I have to clean mine often because of the starch. It makes it brown. But an SOS pad does the trick. I, too, have burned myself with it. More than once. It could use some safety features added. The more expensive one at least has something to rest the hot iron on. But it doesn't turn off automatically. So, short version, not perfect, but the best I have found.
