Product review (5 stars): Be careful when using a powerful drill as the plastic rod can twist up and become unusable if its stuck and you try to force it even worst if its gets stuck up in there
Used this on a roof dryer vent that hasn't been cleaned in 20 years. the vent was totally blocked this thing worked really well. Be careful when using a powerful drill as the plastic rod can twist up and become unusable if its stuck and you try to force it even worst if its gets stuck up in there. Dryer works great again. 10/10 fam would clog a vent again just to use it.
