Product review (4 stars): May not look pretty, but WOW!
I bought this after finding out our dryer vent that runs through the house was not only too small a diameter for a dryer vent, but also probably filled with water. This works great! It catches the lint in the bottom which is filled with water, but the holes in the top half allow good airflow for the dryer. Fair Warning though, it will warm up the room quite a bit, but that was expected. My dryer now finishhes drying before I can finish washing the next load. Like I say though it may not be the most attractive looking thing, but it'll make a great stop-gap while I save to have the original vent redone.
