I had my glass for about 7 months, sent them tons of pictures of how they were curved differently- -especially the quarter windows. In fact the quarter windows were bowed so severely the metal pieces that mount on the edge wouldn't even fit. Also showed them pictures where the door glass were missing several holes at the bottom of the glass making them virtually impossible to install. They even told me that they have a warehouse with every piece of original glass where they compare every piece of glass they sell to an original by placing an original on top and underneath to make sure they are curved correctly. That must be one heck of a huge warehouse just to house original pieces of glass. It only cost me about $1200.00., and they never offered to sell me replacement glass at a discount. They make some great products, but their glass isn't one of them.
