Rated 3.2 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Great Product, Horrible Application I ordered these things to fancy up a bathroom install I am doing at home. I asked several folks how these are supposed to be installed. Alas no one knew. One guy said, use clear caulk, so I did. Guess what, that's not the way they are supposed to be installed Turns out there is a double sided tape that goes between each block which locks them neatly into place. No misalignment, no mess from goopy caulk leaking out the sides. If you can find the tape GET these, The price is wonderful and the product is super. If you cant find the tape forget it unless you happen to be a journeyman. January 3, 2012
Rated 1.0 out of 5.0 by i should have gone to a specialty story Home Depot didn't carry all the extraneous stuff to install the blocks. The only store that did was a specialty store. Even then, the blocks we bought were an odd size, and we were lucky to find what we needed. We should have just gone to the specialty store in the first place, and we would have had everything we needed in one place. March 10, 2014

Rated 1.0 out of 5.0 by Can't use it The 3 inch glass blocks are OK. However neither Home Depot or the distributor in Chicageo sell any 3 inch plastic framing or seperators so they it's vitually impossible to properly install the blocks into the area that you are working in. April 30, 2011
