Product review (5 stars): Great alternative
I have never seen one of these drier vents in the home harware stores locally.  I needed something to rise my vent over my new deck and this did the trick.  It also has the added bonus of shutting 100 % of the time (unlike my old standard vent,) it also gets rid of all the junk and does not clog up -- it does get a bit messy on my deck, but that's life.  The plastic is also very paintable, which I recomend doing if you live in a high sunshine area like I do.  The only con I could find is that the upper section that pops open to clean the unit seems a bit flimsy.  Fortunatly I don't think I will really need to clean it and if I do the whole top section pops off if I remove the upper screws.
