Typical cookie cutter home, probably 1200-1400 sq foot (about all we ever get around here), split foyer, unfinished basement (for the time being).
This is how we run almost all of our dryer vents. Kind of a slick deal, and way cheaper than the store bought dryer box's.
If I could get them to change a few things about our installs I'd say clean the t-stat wire up and run seperate drains for the condensate too. Other than that I think the 2 jobs above turned out pretty well.
