Rated 5.0 out of 5.0 by best purchase ever product description very accurately described the product, very happy. January 14, 2015
Rated 4.0 out of 5.0 by As Ordered, Great Quality - too bad I had to buy four and only needed one The blocks arrived on time and were great quality. I wish I could have bought one as now I have 3 blocks left that I don't need. They come 4 to a box. January 9, 2015
Rated 4.0 out of 5.0 by good product but couldn't use it. We could have used this product if you had a better diagram of the dimensions. Width, depth and height don't work very well on an object of this shape. Since it was not in the store, we had to guess on how the dimensions were made and we guessed wrong by just a little bit and ultimately had to return them. February 12, 2013
Rated 4.0 out of 5.0 by Looks great, nice product This was exactly the product I was looking for. The glass wall looks great. February 5, 2013
