Product review (3 stars): not great
I do not see how this is going to prevent lint and dust from blowing all over your laundry room and ending up all over your house.  I think it will increase the amount of times you have to dust every week.  Dusting is soooo boring.  The hose that came with it is nice and eventually I will replace my existing hose with it.  That is the only reason I did not return the item.  Ultimately I just put a knee high nylon over the end of my existing hose
and plugged the outlet to outdoors.  My main goal was to keep the heat and humidity in the house over the cold nothern winters.
