I was asked to verify the reviews for penguin windows and it appears to be you either love them or hate them. We had our sales reps come by to look at our problem window only to discover that the previous owner hadn't had his replacement windows done correctly. We hadn't noticed it because we have been working on all the other deferred maintenance in the house and yard.
I will state that we didn't feel pressured, the quality of how they were made was impressive. We purchased them for the entire house not just the one window, so I will wait to see how the install goes and how well they work.
