Product review (5 stars): My dryer truly loves the Acme Dryer Booster!
This dryer booster has been great.  I have had it installed for a few weeks now and it is working great.  It took me about 15 minutes to install.  The installation was simple, simple, simple.  My duct run is approximately 25ft and has four elbows.  I also installed an additional lint screen (Lint Trap with TURN KEY LID FASTENING SYSTEM by Direct Fans).  The additional screen installed between the dryer and the booster keeps any lint from settling between the booster and duct outlet (22ft +).  Now I just need to keep the short run (3ft) between the dryer and booster clear from any lint build-up.  The end result to all of this is that my dryer works a lot less and my drying times have been cut in half, saving me big bucks on my electric bill.  This is one of the better investments I have made lately.
