Query: Ineffective

I basically found the kit to be ineffective in getting the lint out that by-passed the dryers filter. The vacuum attachment was kinked from being stuffed in the small box --- and so far, the kinks have not come out. The tappered brush does a decent job of removing lint that is easy to get to but is difficult finding the way to turn it to go farther down the vent. I have not used the big round brush because the dryer must be pulled out of its nook. I can not recommend buying this item.
