Product review (3 stars): At a Great Expense. It Does What It's Supposed To...
It vents the exhaust to the side, instead of the back, just like it says. I'm just not that impressed with the price or workmanship of the item. Anyone with a bit of spare time and mechanical inclination can probably make this for substantially less from found pieces at a home improvement store and get the same or better results. This is probably $10 or less (based on the economies LG or whomever buys these parts achieves) that sold for nearly $80. Capitalism at it's best, I guess. It included NO instructions, so I had to piece together the design (fairly logical) based on mechanical aptitude and experience. The joints are sloppy and poorly designed for something of this price. Sure, it includes a little plate to block off the rear exit (that also fits poorly), so I guess that's the $60 value-add.

It's just a poorly designed afterthought accessory kit that does indeed do what it's supposed to, but at a huge expense with limited value. I'd really research to see if this is actually what one needs, of if another alternative (new location for washer/dryer, rerouting external vent, etc.) might exist.
