I don't know where to start.... It was a great experience all together from the salesman to the install it was a great experience. Windows are not cheap any way you go. If you go cheap you pay for it in the end by replacing or having issues with the window (know from experience) or you pay it up front and don't worry about it again. I told the salesman up front that I didn't want to put Lamborghini rims on a Yugo, but turns out it was a good investment. I was doubtful on the electric bill being lowered but already hear the A/C running less than it did and it is now warmer outside. The noise was reduced significantly to near zero. Difficult to hear cars pass by or others talking in the back yard. These guys are fast and efficient. My only complaint is the city coming to inspect the windows for the permit that was issued. Its been nearly two weeks and they are MIA!
