I got very good installation and service for my system. The design seems optimal and now I'm earning $ most of the year rather than paying $$$$ each quarter. Got very good answers to my questions and good help. Had trouble with wifi because of the distance to the router but that was fixed with a hard wire and now I have even been checking the system while travelling OS. I've recommended PE to several friends who have all reported similar experiences, These guys really know what they're talking about.
