Product review (4 stars): Could be improved with little effort.
This cent seems like an improvement over the contractor grade vent, but not much.  The plastic construction is thin and the lid is merely friction fit.  This could be a problem as the air box is under some pressure when the appliance is on.  I would like to see sturdier plastic and some type of lid latch or crew on capability.  Installation is straight forward, but with my situation, imy existing vent was built into the stucco. I had to cut the sheet metal shroud off flush with the wall with a Dremel. Then had to drill pilot holes with a masonry bit and silicone the vent to the wall.
