"I was turned down by ADT because of my credit score. DEFENDR shipped my system the next day. It took me 20 minutes to set up in my apartment and the app works flawlessly. Highly recommend!"

"The fact that I'm not locked into a 3-year contract is huge. The touchscreen panel is super responsive, and the motion sensor ignores my 30lb dog perfectly. Half the price of my old system."

"Setup was incredibly easy. No drilling holes in my walls. When I tested the alarm, the monitoring center called my cell within 15 seconds. Incredible peace of mind."
