Product review (5 stars): LintEater - Excellent  Product!
Thank you very much for this excellent product.

We have been having problems with our dryer taking forever to dry our clothes and I discovered the vent was jam packed with lint. I attached a small cleaning brush to a "fish tape" of the sort that electricians use and managed to work it through the entire vent. When the scrubbing produced no additional lint, I hooked the dryer back up, but still no air flow.  I have about 18 ft of dryer vent hidden in an inaccessible partition between two floors. I could see that about 3 ft at each end was clear via visual inspection. I naturally assumed that I had removed all the obstructions because my brush could travel freely through the vent.

Looking for any info on this problem, an internet search found this product. The web site instructional video is also excellent. Since my only other option was to run new vent or tear out the old one, it seemed worth a try. The flexible rods navigated the vent without any problem and an amazing assortment of lint, twigs, leaves, etc came flying out. Problem solved and our dryer is now running perfectly! To make it even easier to use, I fed the push rod through a two foot metal pipe. While my right hand held the drill, I held on to the metal pipe with my left and this prevented the last push rod from a tendency to twist up on itself.

This product should be sold in every hardware, plumbing and HVAC store. I especially like how thorough the kit is - complete with useful extra fittings and DVD.

Modern dryers will turn off or kill the flame when air flow is impeded. Older models will just continue to run at max temperature - creating a fire hazard. So you might have someone return a dryer as malfunctioning when it is simply a lint blockage.

All in all an elegantly simple and 100% effective product.
