Rated 5.0 out of 5.0 by great window..... great window...custom made.. arrived quickly, no problems at ALL March 27, 2013
Rated 1.0 out of 5.0 by Fell apart due to poor construction I was really excited to receive this already assembled, until I received it. I had already built 7 glass block windows for my basement, so I have a good idea of strong, quality construction. This window fell apart at the silicone seams when I opened the box. Yes, it was shipped; however, it had no spacers between the blocks only a slight amount of silicon. I accidentally dropped a well constructed glass block window from a basement window to the basement CONCRETE floor, it didn't break. July 17, 2013
Rated 5.0 out of 5.0 by product as explained window came as stated and installation was a breeze, quality was tops. appearance after install was better than I had hoped for. March 3, 2015
Rated 5.0 out of 5.0 by Product arrived without flaws The product was well packed and strapped to a wooden base (pallet) Rough opening was well prepared with proper dimensions and Installation was not difficult. The product may be a bit too heavy for some. It provided the light as well as privacy. Completely satisfied with product and the results. July 22, 2015
Rated 5.0 out of 5.0 by Other than price this product met or exceeded all expectations. Beautiful window! Had it installed in our bathroom. Let's in tons of light and will not rot like the window I replaced. Contractor had no issues installing. I ordered 2 more windows from a different company because of a vent feature that this one did not have. They were cheaper but my contractor said they were not as good quality because of the type and amount of silicon used. You get what you pay for. April 1, 2014
Rated 4.0 out of 5.0 by Good solution for oddly sized basement window Bought the pre-assembled glass block window thinking that it would be more professionally done than I could have done myself, but I was wrong. The glass blocks are just held together with clear caulk, so I could have saved some money and bought the blocks individually. It was, however, easy to install and I am happy with the end result.

Rated 5.0 out of 5.0 by Glass Block This was an excellent buy for our remodeling of a bathroom. Ordered online and received within a week, plus they had free shipping. Great construction and good directions on how to install. They should have mention to use their premiere mortar spacers to get the proper fit without error. But all and all this was a great investment. Looks great in the bathroom. Ready to use again. January 25, 2010
Rated 3.0 out of 5.0 by Looks Good The window looks good, but it's bowed in the middle. The window deviates 3/8" from the middle to sides. The window specifications are incorrect in the description. I called the manufacturer before I framed the opening and he confirmed 46.5 x 35.5 assembled dimensions, but when the window arrived, it was 46.5 X 34.5. I had to modify the sill and weatherproof again. Between the bow and wrong advertised dimensions, window was more difficult to install than it should have been. January 29, 2013
