Review: Locally they sell these for 8 dollars each. And for some reason there's SO MANY OF THESE IN OUR APARTMENT!!! Why on earth do they put so many light holes when building these apartments?? My brother has 12 -- I KID YOU NOT -- 12 light holes in his livingroom ceiling, and it's not even a big livingroom! Needless to say, this product has brought light into our lives.
