Stay away from these crooks. I have never been so mis- lead from a business my whole life. This business is family owned and they all are in it for the dollar. They will be nice until you sign the contact then German (owner) will cheat every last penny from you. They told me it would be $99 total install price then $35.99 monthly. They charged my credit card 4 months after the install for over $700 dollars, and they refused to get me a itemized bill??? Then the $35.99 went to $44.99 monthly and baited me into a 3 year contract not the 2 year I agreed on. Add it up - $700 down + $1,700 (3 years motoring) This cheap ass alarm that never works right cost me $2,400 and cost them $350.....BEWARE of this Mexican family owned business. Go to ADT Corporate in Aurora for your security alarms.
