Product review (1 stars): Poor Quality Construction - Not Worth the Money
This product is very poor quality especially for the price.  I ended up returning it and getting something at Home Depot that I was able to make work with essentially no modification.  I bought an extension made by Everbilt and reversed it (the intake/exhaust were at 180 degrees - by turning one end around they are on the same side and it works great). The Everbilt is much better construction, lower price, and is working great. .
