Product review (5 stars): Perfect for a dryer that had to be moved!
I hesitated to order this.  There are a number of great DIY indoor vents you can make.  I needed something that mounted to the wall.  Last year my house caught on fire and our water pipes became electrified.  The home was 100+ years old and I decided to run new PEX hot and cold lines to all the rooms and both kitchens (duplex).  New sewer line was also installed but forced me to change the location of the washer and dryer.  The hall way now had no place to vent the dryer to (outdoors)  While I'm thrilled the heat from the dryer was captured inside, the lint was also free to fly around.

This vent-trap is brilliant.  Easy to disconnect and clean.  Simple to setup.  It was installed using the enclosed zipties without any trouble at all.  Granted I'm mechanically inclined, this may not be as easy for others.  Price and value are what motivated me to buy!  Thanks for a solid working basic product that fit my needs!
