Product review (4 stars): Awesome product but...
So I bought this from a different vendor and would like to assist my friends on Amazon. I bought a new house and the next day walked out side to do something and noticed the dryer exhaust was barely venting (older house). Que up a trip to the store and I found this thing. I was so excited about saving money I brought it home and slammed it into the dryer exhaust without reading the directions. Five minutes later I was cussing for hours because one of the rods untwisted and it was stuck so far in my dryer exhaust, I couldn't reach it to get it out and it completely clogged the vent.

After hours of contemplation, I finally devised the perfect plan. I could see the end of a rod with a flashlight. I attempted to slide another rod to that and screw it in, this didn't work due to the rods being flexible. I then took a bolt and taped it to one of the lint eater rods and finally got it pulled out. After removing it, I decided to actually clean the vent. I read the instructions and followed them to a tee and bam. Lint went flying everywhere out the exhaust and now the dryer works like a charm.

So here is a few pro tips. 1) Read the directions! Don't be like a caveman as I was. 2) if your exhaust is long there is an extension kit available. 3) I highly suggest you tape the connections with duct tape so they don't unravel by accident. 4) Never put the drill in reverse.

Follow these tips and your experience should be just as good as the second part of mine.
