Product review (3 stars): Works, but awkwardly
Ok, it works fine, the removable filter is ok, but you have to run dryer hose above your dryer, and a second hose back down and out the exit.  Note that there are no holes in it to mount it, and we had to drill several and get it mounted to drywall.  It isn't that great to look at if you have a nice laundry room versus a basement hidden one.  However, it's good at efficiency, as that heat would be wasted otherwise.  Also, the screen does a great job of keeping lint out of your living area.
