Product review (5 stars): Great for Preventative maintenance and not too severe clogging of vent pipes
This product is easy to use and is effective as long as the lint in your pipes has not totally hardened and caked up.  It worked very well on half of a 23 foot vent pipe, but unfortunately I had to dismantle the other half in order to remove the caked and hardened lint.  I think it is easy to use and would be good on most dryer vent pipe obstructions, especially on shorter pipes.

Now that I have my vent pipe unclogged, I am looking forward to using the Gardus LintEater for preventative maintenance. It is simple to use and works very well on all of the but most the difficult jobs.
