Product review (3 stars): Works Great, but Installation is Difficult
This worked well for allowing me to side vent my new LG dryer.  Word of caution, installation is quite difficult as you must feel things out because you cannot see what you are doing.  The hardest part was getting the ducting taped properly once installed.  Word of advice, find someone with small hands and give them leather work gloves.  Big hands will have trouble fitting, and the leather gloves will keep you from getting as cut up as I did.
