Rated 4.4 out of 5 by 26 reviewers.
Rated 5.0 out of 5.0 by Excellent window This window takes all the headaches out of the project, once the old window frame is removed I installed it with silicone. My install was time extensive as the old window frame was embedded in concrete on 4 corners but it still only took 4 hours. Insulating value was greatly incresed over the old window I do recommend to use a good quality silicone with a short drying time if you decide to mount it this way. You will be installing it with a good sealant depth to seal out the weather and to create a strong bond for security purposes. November 15, 2010
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 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 great window..... great window...custom made.. arrived quickly, no problems at ALL March 27, 2013
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 5.0 out of 5.0 by Great window and free shipping Replaced all 4 of our basement windows with these (2 vented and 2 non-vented). All arrived within 3 or 4 days of ordering them online and in perfect condition. The packaging was excellent, all were marked fragile and glass. UPS did a great job of getting them here undamaged. The price was great and the difference between buying the blocks and assembling them myself or buying these preassembled was not worth the time or hassle to me. There was some variation in the joint thickness as mentioned in other reviews but it was minor and the windows fit well. They seem well constructed and were made in the USA. We have a cement block basement and the existing windows has a 4 inch mortar "sill" . When removing the old windows I also removed the old "sill" and was able to fit 16 inch windows in the 2 block tall opening. The larger windows allow much more light in now. The new windows seem much more secure and weather tight than the 30 year old windows they replaced. All in all we are very happy with the purchase, how the shipping went, and with the value for the money. It was also one of the best "bang for the buck" home repair/improvement we've done in a while.
