Product review (5 stars): Fit for use
Because the footprint of our new LG dryer is larger, it didn't fit into the previous space.
The new dryer required a rigid or semi-rigid vent in order to maintain the warranty.
Though a challenge to install, this vent works as envisioned, and makes the dryer fit substantially closer to the wall.
We put a Whirlpool Laundry 1-2-3 Worksurface (WW29000) on top of the new washer/dryer so stuff won't fall behind either.  Not a perfect fit, but it works well.
