This Indoor Dryer Vent works ok, but you have to add water to it to catch the lent, which is not that bad, but if you don't forget to empty the water out when you start traveling, you may get wet or have water on the floor.  One negative that I read about it, is that you have lint all around where it is installed.  I have not found that to be a problem so for, as long as you put the water in.
