The two stars are because they MIGHT be good. I wouldn't know though, because I never heard back from them. I set up an appointment with them to come out and look at my window to give me an estimate on how much it would cost to replace it. Their guy came to my house, did some measuring and said he would email me with the quote. I never heard back. It's funny that this isn't the first company to do this. I guess it's a window company trend.
