Product review (5 stars): Gardus LintEater
The dryer vent cleaning system is a must for any homeowner. The Gardus LintEater cleaning system performs as described and decreased the drying time.  It was taking 2 cycles to dry anything and now it's less than 1 cycle.  We have three 90 degree turns in the dryer vent PVC piping going outside.  We also purchased the extension set to clean the whole pipe (18 feet).  We made at least 20 passes until all the lint was gone.  I feel safer after vacuuming and emptying 6 canisters of dryer lint from my dryer vent.  Just follow the easy instructions and anyone can use the Linteater.
