Product review (5 stars): This works!!!!!
Ok.....I have a single story house (six years old) with the laundry room in the center of the house. The dryer vents straight up about 9 to 10 feet, then a 45 degree turn, then another 5 to 6 feet to an elbow which exits through the exhaust cap out the roof. About twice per year I have always used an electric leaf blower to blow it out. It worked decently but lint would always catch on the exhaust cap and my roof pitch is so steep that I will not go up there again. (tried once, not again)..What I do is get on a ladder to the edge of the roof and use a long pole with a brush attached to the end of it and work it around the roof cap until the lint is broken free. That being said, I never knew how much lint was remaining in the 16 to 18 foot vent run..Today I received this, read instructions. Used a cordless drill (but going from the laundry room out the top (I had no other choice) Nothing came loose at all (not even close to lose) thanks to the items screwing on clockwise and running the drill clockwise made everything stay on tight.

After using six of the eight extension wands I finally couldn't get it to go any further.....I stopped/went out to see if I could see the brush attachment in the roof cap at all (I didn't) but it must have been very close because lint was being pushed out of the cap (with no airflow because nothing was on other than the brush itself). I went back in, ran the brush a little more then started pulling it back out and a bunch of lint came with it (a plastic shopping bag full).....I then got a leaf blower to blow out what additional lint I had loosened...(OH MY G**) the amount of lint that came out onto the roof was staggering! I ran it up through the roof once more and got zero lint out! It's all clean now.......So for those of you who think a leaf blower works (it does) but you're not getting all the lint with a leaf blower (like I thought I was).....I had to purchase this item but I had to purchase the extensions from another seller which I thought was odd. I had to get 2 different packages shipped instead of buying everything from one seller..But it's worth it in the end. This thing can be reused over and over and it took NO TIME to do the job. Thanks
