Heed the other warnings.  I got this yesterday, washed it (smelled a bit of plastic), dried overnight.  Then knowing what others have said about the suction being poor, I cleaned the suction cup with rubbing alcohol to make sure it was free of any oils.  I hung it INSIDE on a clean window in 50 degree weather EMPTY.  Within 5 minutes it fell to the ground.  The suction cup fell off as well.  The clean plastic piece became detached from the red piece and cracked.  All of this under perfect conditions UNLOADED.  I can't imagine the garbage suction cup standing up to any kind of weight.
