What is it that makes cavo so great that they say their the best and can take over any system they go in? I've been around along time, long enough to hear all the same bull from dozens of other companies that have came and went, seen many worthless installers and good installer move from one company to another, my self included and have yet to see a company that great. I've learned from my experience to stay clear of the companies with the representatives that like to run their month about how great they are! They run their month and try to sell you a line of crap in hopes to camouflage the fact that they are the same as the rest.
