Had them come out for a quote about two weeks ago. The gentleman was very friendly and professional and you can tell they have a high level of customer service.... but the buck stops there. I got quoted 17k for just my first floor windows and 35k+ for all my windows. Now I'm ok with paying a premium for security but this is straight price gauging since they are really the only game in town for his product. After hearing the quote I wanted to check the techs honesty gauge and asked about ROI. The tech played it safe and didn't give me a definitive answer, but did allude to say that he has heard of several people recouping almost all of the cost on sale. I work in the mortgage industry and have reviewed thousands of appraisals and have yet to see a positive adjustment for this feature... in laymen's terms, there is no significant tangible value. Granted they may be too new for this to be reflected in market trends, but ask yourself... would you pay 35k more for a house with these screens? I think I'll just get a security system and wait for them to have some competition in the Phoenix area so their prices actually become reasonable
