Product review (3 stars): Hmmm... how much?
This is a lot of money to pay for some regular ducting. The only thing special about it is that one of the lengths has a small tab welded on the bottom to allow it to be screwed into the matching mounting tab inside the dryer.
Apart from that, the ducting is the bog-standard ducting you buy at your local hardware store, including the elbow.

I actually MADE this kit myself from local hardware ducting before I thought "you know, I should just pony up the extra money and get the real LG version, just in case". But in reality, apart from that mounting tab (which I could have replicated using a worm clamp and a zip tie), my version was actually BETTER because the vent that exited the side of the dryer in my version went all the way to the mount on the wall instead of just to the inside edge of the dryer.

Would I buy this kit again? No. Am I using it right now? Just the first arm and the elbow. I used regular ducting for the arm that exits so I could do away with one unnecessary joint and have the vent go all the way to the wall.
