Product review (5 stars): A must have for apartment dwellers or anyone whose dryer does not vent to the outside!
When you live in an apartment, or have need supplemental heat during the winter, this little device is for you.  The lint trap is designed to catch any excess lint coming out of the dryer and disperse heat throughout the room from the dryer.  As my dryer is not vented to the outside, this was an absolute MUST for me.  I love it!
