Product review (5 stars): Wonderful Tool
My dryer was barely heating up.  From experience, I suspected the problem was a clogged vent.  But, now I had an inaccessible, 11 ft duct to deal with.

Within 15 minutes of having started using the LintEater cleaner, I had removed enough fiber to open a small paper factory.  It did take a little extra support from my shop vac to remove the last plug.  The shop vac adapter helped streamline its role.

My dryer was soon heating up.  My towels came out dry in a reasonable amount of time.  This was an easy-to-use and effective product.
