Product review (4 stars): Worth the $
It really works!  I do put more water than the instructions states.  I figured out a way to stop the fly away lint that comes out the air holes! Because trying to get a stocking over it just sounded to crazy to me! *I bought the handy wipes from our local 99 cent store, folded it in half(2 works better), sewed a string into the top(for a draw string), sewed some velcro to the sides(open and close), wrapped it around the top where the duct connects with the top, pulled the drawstring tight around the top(tied it in a bow-for easy removal) closed the sides with the velcro, and no lint came out!..it's not hard to do at all.  I make sure my little invention is wet(just to ease my mind)! it's reusable too!..* Do not leave your home while drying cloths, because you never know what may happen, even if you don't try my little invention, lint+heat can = fire*  The reason for the 4 star instead of the 5, is because it's not that attractive, was a little hard to figure out where to put it since i have the  'washer/dryer mounting stand, the dryer is on top and there's really no where to put the vent, of course i figured out a way, because i didn't want to get a longer duct to add to the unattractiveness! So when it's not in use, i just set the duct and vent on top of the dryer and the bottom part I just put in a cabinet until i need it again. All in all, works great(with a little work) :)
