Review: Much cheaper than buying locally. - 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.
Review: Great experience - The order came in timely, and our expectations were met.
