Product review (1 stars): flimsy POS
flimsy, in no way seals the window from outside air (it could at the very least have come with some foam tape) and best of all? it's too short when fully extended to run the full length of my window. it's my own fault for not measuring, but i just couldn't imagine that they'd produce something designed to go into a window that wouldn't actually fill a standard-sized window.

in short: you'd do just as well to stick the hose out the window and surround it with blankets. looks equally unprofessional and is twice as effective.
