Product review (4 stars): Well worth the money
I had recently spoken to our chimney sweep about cleaning our dryer vent and he quoted us about $200.00 to come out and clean it.  I saw this on [...] and decided to order it.  I came to Amazon and saved about $10, plus free shipping with Prime.  I also bought the extension kit because our run is very long&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/GARDUS-INC-R-3203612-12-Dry-Vent-Extention-Kit/dp/B001652LO6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">GARDUS INC #R-3203612 12' Dry Vent Extention Kit</a>.  Anyway, we cleaned out the vent today and I can't believe all the gunk that was in there.  I don't think it had been cleaned since the house was built over 20 yrs ago!!!  There were a few issues, such as the shop-vac adapter was too big (diameter too wide) to fit on the standard shop-vac hose, so I had to rig up something with a tube from my blower combined with my shop vac to get it to have the proper dimensions.  Other than that though, it worked as advertised.  It was easy to connect each extension when I needed it, and it went through like a trooper.  My gunk must have gotten wet at one time, because when the brush got to the inside, it just stopped.  I ended up taking off the dryer hose where it was connected to the house vent, and all the gunk had gotten stuck there (It was hard-packed).  Just pulled it out and voila!!!  You can actually see the air coming out of the vent now, where before, you could barely feel it coming out.  I think it was well worth the money as it saved me over $[...] of having a pro do it, and I can use the tool a couple times a year to keep it clean with no added expense.  Hopefully it will be even easier next time because it will not be so clogged with lint.
Very satisfied with the product.
