Rated 4.0 out of 5.0 by only one came broken, I think that is pretty good for glass.. but I will never try to do the 3 inch block again,,, 4 inch is much easier hard to install nicely,,,4 inch is much better to install straight July 2, 2015
Rated 5.0 out of 5.0 by Thinline Glass Blocks - 10 pack I use these glass block to make gifts. I make decorated lights that have many uses. I WISH you sold all the other sizes so I would not have to go other places to purchase them. ie thin tall ones and other shapes of them. December 9, 2014
Rated 4.0 out of 5.0 by Glass Blocks for Craft We bought these for a Christmas craft in which we drilled holes to put lights in. The drill bit dulled after only 14 blocks (we're doing a total of 80) - and it's no cake walk. The quality is great, just a bit challenging for what we wanted to do. November 16, 2011
Rated 1.0 out of 5.0 by Nice blocks but not for Exterior windows/walls We wanted to replace 4 old 9 FT X 6 FT windows with bars, hoping to eliminate the need for those ugly bars. I have chosen the supposedly more secure way of doing it, using mortar, metal anchors to the surrounding wall and metal reinforcements. We have made sure that the spaces between the bricks were filled with mortar that we pushed to make sure the space to assure maximum safety. After we finished the last window, we let it dry overnight and on the next morning, I have asked on of my employees to check how secure the window is. He took a very small hammer and hit one of the bricks lightly, the brick was shattered very easily. From there once one brick was broken, we have managed to separate other bricks very easily . I am shocked that the bricks can break so easily and was under the impression that they are as strong as regular cinder blocks. Needless to say, we have decided to take our losses with this one wall installed and have returned over 165 glass blocks. My recommendation to you, buy one of those glass blocks and hit it lightly with the smallest hammer you can find. You will see what I am talking about. March 3, 2015
Rated 3.0 out of 5.0 by Very Poor shipping packaging This is my second order of glass blocks, the first order of 12 had four broken ones. The second order, had two cracked blocks. Very poor shipping containers. I will have to return the broken blocks for credit, just a small hassle. January 24, 2014
Rated 5.0 out of 5.0 by Great Value! I just placed my second order of these blocks. They are cheaper priced than any where else i have looked. I drill holes in them and use them for my crafts... and they look great! They come nicely packaged in a sturdy box. August 23, 2014

Rated 5.0 out of 5.0 by Christmas gifts Used this as a Christmas gift. Stuffed it with Christmas lights and wrapped a bow around it after drilling a hole on the side. Big hit, beautiful! January 1, 2015
