Phone calls never returned. Mail box always full. E-mails never answered. 800 number offers vacation pkgs. No menu for speaking to a customer rep. What a scam. Come into my town offering a free dinner and walk out with $4538.00. Darin Kendrick is the Sales Person. Danny (no last name) installed the equipment. Turns out he recommended more detectors than we needed. Why not? That pads the cost of the equipment. We are disappointed and angry. The detectors seemed like a good investment at the time. Offered attractive discounts if we paid in full. Lesson learned. Don't pay for anything until all services have been completed. Next business that offers me a free dinner to listen to a sales pitch will be told what to do with the dinner.
