I used it as soon as I received it. A borrowed trap sucked inside - the brush got stuck and fell into the dryer. I couldn't see it at all. I called a couple of mechanics but got no answer. I decided to use an old all metal hanger, straightened, to hook and pull out. It took a little fiddling, but somehow I caught it and pulled it out. I advise against using the brush in the trap area until they come out with the brush latch.
