Product review (5 stars): Great Product. I have had 30 Feet of dryer ...
Great Product. I have had 30 Feet of dryer vent (mostly straight but one U type turn). I also had bird nest in my dryer vent. I called my association and they did remove the bird nest from outside. However, When I use the tool that came with this product, I was able to remove leftover from the nest. I guess whoever did took out the nest did not completely did their job.

I then followed direction (checking if air is coming out from dryer vent properly or not as if might have some blockage, clockwise direction, electric tape, I also added duct tape on it) and did this inside out and was able to clean the vent properly.

Note: It's always good idea to check the air movement of dryer vent when dryer is running. Not every time but once in a while is good.

I had total blockage because of nest and as air was not flowing outside at all the lint has so much moisture as well.

Good thing that I did this with this product, I now also have metal filter as well outside so that birds can't get in...

I'll still be cleaning this once every summer ...

:-) . Thumbs UP.
