I like them. More important my wife likes them
I moved into my 30 year old house about 5 years ago. By the second winter I relized I need better windows. I started researching and found a couple of web sites that reviewed vinyl windows. Over the course of the next few years I would review the site to see what was going on in the Houston area. Randy's name from Ultra Windows came up several times all in a positive light; about the job quality and importance to detail. When I got ready to purchase windows I already knew who I wanted.
While I was waiting to for my order to come in and be installed I mentioned the window to the two people either side of me and showed them the broucher I had. Both ordered new windows from Ultra Windows. Both had several different venders come in and Ultra windows was easily able to beat their price.
All in all I had the windows about two weeks and we have had a cold spell (Cold for Houston). I notice the house staying warming and no inside condensation forming on any of the windows.
