Great draft/light blocker and easily installed!
This works just great for me.  I recently pulled up carpet in the hallway, which resulted in a rather large gap at the basement door.  When the air is running, it is pulled under the door to the basement quite a bit.  I added this item with relative ease, which works surprisingly well considering it is just attached using velcro and simply hangs from that to the floor.  The key in cutting it to size is to measure the inside of the door when it is closed and cut slightly larger to see how it fits.  Since one can remove the flap pretty easily and reattach (due to the velcro attachment), it's easily re-sized, if needed.  I wanted mine to fit snug to each end, so I cut it slightly larger and made only one more cut to make it a perfect fit.  Blocks light and drafts from beneath the door.  Love it!
