This company called and called and finally I allowed them to come out for demo for a $50 Home Depot gift card.  The system was outragously over priced but did receive a gift card.  $20 gift card that is.  I called the person that called us the day before the appointment and now acts like he is just the scheduler.  I asked him where my other $30 is.  He said oh, they give out $20 cards, not $50 like some others.  I know he clearly offered $50.  These guys do a bait and switch just to get in your house.  Run from this company!
