Product review (5 stars): Great if you have limited dexterity
After struggling for a few hours to connect semi-rigid flex vent to the back of a one piece laundry center, I ordered this. Arthritis in both hands makes it difficult to use only the rigid vent with worm drive clamps, especially in tight areas.
I've used this previously in a different home, but wasn't able to find it locally. Within fifteen minutes of receiving the package, I had it put together and connected to the vent outlets. Simple assembly - follow the instructions in the packaging, and look for the raised directional arrows when installing the end pieces to the vent.
