Looks silly but GREAT PRODUCT!
Bought this for my son to use at college to block out the light when trying to sleep in his dorm room. He goes to bed earlier than his roommate who likes to stay up late.  It looks a little silly but it does the job and blocks out the light so he can get a good nights sleep. The only problem we have had is we can not get it properly folded back up into the holder when not in use so it stays up and open all the time.
