Bests & Worsts Reviews from Amazon

I purchased this package for a home in Venice Ca. The base unit could not hook up to their cell system. Simplisafe sent out a new cell card. Still no reception. They sent out a completely new base unit. After a month and a half the system still does not work. I will try to return the complete system. Simplisafe did try many times to trouble shoot the system unsuccessfully. Customer service although not helpful did try. UPDATE: Do Not Be Patient. Amazon took the alarm system back but kept 20% $100.00 for an alarm system that never worked.
