Product review (4 stars): Headache to install, but your only option to side vent your LG dryer
Necessary if you want to side vent your LG dryer, but it is a pain in the @ss to install. You essentially have to work blind inside the dryer, but once together it seems solid.  I wish the duct did stick out from the side an extra inch.  Would have made connect the flexible duct easier, but 1/2" was just barely enough.
