Product review (5 stars): Winner!
Does EXACTLY what I need it to do.  I own a yoga studio where the laundry room was a bit of an after thought.  It is placed right smack in the middle of the building, and in order to vent the dryer outside, it would be expensive.  I was nervous about buying the lint trap, but I am glad I did.  It gets a bit toasty in the room, but we allow the heat to escape through the drop ceiling.  I have had no issues with lint flying everywhere... seems to stay in the trap for me.
