Product review (5 stars): Works as advertised
I have a long dryer vent run through a finished ceiling space, so keeping it clean is a better option than having to open up the vent pipe.  I used this&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Gardus-RLE202-LintEater-10-Piece-Rotary-Dryer-Vent-Cleaning-System/dp/B0014CN8Y8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Gardus RLE202 LintEater 10-Piece Rotary Dryer Vent Cleaning System</a>&nbsp;with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Gardus-R3203612-LintEater-12-Foot-Extension-Kit/dp/B001652LO6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Gardus R3203612 LintEater 12-Foot Extension Kit</a>.  I used about 18' of the tubing to reach through my dryer vent run.

In the end I pushed out a giant lump of lint that was choking the vent and slowing my drying times.

The pieces of tubing connected together really easily.  I tightened them together with pliers and tape to make sure they stayed connected the first time.  In the future I probably won't bother with the tape.  Running the tubing and auger in clockwise direction should keep the tubing together all of the time anyway.

The ends of the tubing is about 3/8" in diameter.  If your drill chuck is exactly 3/8", it might be tricky to fit in the end.  I did my work with a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Milwaukee-2410-22-M12-12-Volt-3-8-Inch-Drill-Driver/dp/B002EEP4VK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Milwaukee 2410-22 M12 12-Volt 3/8-Inch Drill/Driver</a>&nbsp;and it fits easily.  On its lowest power and speed settings, the Linteater was just fine augering out 18' of dryer vent.

The tubing slid in and out of the vent without a problem.

The kit comes with adapters to attach a shop vac or leaf blower to create airflow in the vent while your auger brush is loosening up the lint.  I didn't try those out at all, but it seems like a good idea.

It did the job, and I didn't have any problems with it.  I'd recommend it to others.
