Product review (5 stars): A product that works so well, you want to show the neighbors
Let me say a few words about this awesome product...

I purchased this since my dryer was no longer drying to the degree that it once was. We had our heating element go out on our brand new dryer after about 2 years of usage and we initially attributed that to a fluke lemon heating element. No big deal. Then when the new element went in, we thought that it was much weaker than our old one even though it was the same thing. Our clothes would get hot, but not really ever dry.

We have dogs, so there is a lot of lint and dog hair that ends up in our lint trap or passing through the exhaust. I bought this product because I had a suspicion that we had a buildup...and boy was I right!

The instructions first tell you to check the outside vent for blockages. The way that these vents should work (or the way mine works at least) is that there is a flap that opens when the dryer blows and shuts when the dryer shuts. That part worked fine for me, but there was a metal grate in front of the exhaust that had a good couple of inches of solid buildup. One side of the clog was even starting to darken as if it was toasting. The instructions in this manual say to remove this grate and I did.

Now I could have stopped there and my dryer would have probably still worked 100% better than before, but I continued with the instructions. My exhaust is on my roof and my roof is steep, so I decided to run the rods from the inside. The first thing to do is prop the exhaust flap open. Done. I then used the shop vac attachment and ran the rod through the small hole on the attachment. With the vac on, I added the poles until I reached the top of the vent. First I will say that the flexibility of the poles is perfect. They are sturdy enough to no collapse, but flexible enough to round corners and move pretty easily through the duct. My duct has an immediate 90 degree turn towards the roof and it handled it without issue.

When it was all said and done, my shop vac was halfway full of lint! This is in a 4 year old house! As a caveat, there is no telling how long the grate was blocking the airflow and I would guess that caused a lot of buildup further down the duct.

I even used the smaller, long brush on the inside of the lint catcher in the front of the dryer and pulled up quite a bit of lint there. I was really quit impressed! I washed the guest bed sheets and they came out dry without any extra runs! This thing should pay off from the saved electricity pretty quickly, plus I can use it over and over again and loan to friends.

I was so shocked by how much lint came out, I had my neighbor come over and check it out! Guess who has this kit at his house right now?
