I would give this company no stars if I could. BE AWARE...company has no customer service at all, from owner Brett Benson to installers. After spending $5150. I would never recommend them. The lead installer Don actually told me that they always make mistakes but "cover it up" before you notice it!!! Unfortunately they are the only game in town that makes this product or I am sure they'd be OUT OF BUSINESS. Here's a link to my comments on their facebook page. They deleted the first one I posted on 10/12/15.
