Do not do business with these people, its a nightmare that never ends. My system cost over $40K and there have been endless faulty parts and it still does not work properly. Their business practices are absolutely horrible on top of the technical issues. Every time they tell me its all fixed now but its not, and they dismiss my concerns since I don't know what I am talking about. The only good thing I can say is that they do keep coming back but of course we would be in court if they didn't.
