Product review (2 stars): Not a perfect fit for all venting systems
Not a perfect fit for all venting systems. We had two pieces break in half in our venting system (not where the pieces connect) and had to take apart our venting underneath the floor. This could have created a very expensive service call but luckily, the vent was in the furnace room with an open ceiling. We ended up cleaning the different sections with the brush and drill one by one.
Pros:
The brush and poles work great with a drill. Makes quick work out of the pipes and cleans them well.
Connectors stayed connected throughout the process
Works great on straight pipes or with slighter bends.
Cons:
Avoid piping that has multiple turns. Gathered the lint in them and didn't push it out. We found it when we took the piping apart.
Can break with too much pressure
This a fairly good product and great concept. I just wouldn't recommend it universally for everyone.
