    The Ring Alarm is by far the beat Alarm system I have ever own. It does exactly what it says. It only cost $100 a year for monitoring instead of $50 a month. I will never own another Alarm.

    The Ring alarm system is a good one for those of us who don't want a company-monitored system. It's great to be able to use your smartphone to check on what's going on at your house. I also have a Ring doorbell.

    What can I say...they do what they need to do and tell your Ring Alarm system if a door/window has been opened. You should definitely have these sensors on all doors/windows on your house. While a motion sensor will work as a backup if someone gets into your house, I'd much prefer to know someone is breaking in BEFORE they are inside the house.

    These are great because they are not just for windows and doors in your home. We have added them to my husband’s work trailer due to the increase in car break ins.

    Unit only came with 1 Contact Sensor. That worked for the front door but needed an additional one for the patio door. System should come with 2 I would think but worth the extra dollars for the piece of mind

    The sensors that are captured by the Ring base station work quite well. However, the size of these sensors are physically too large. They look hideous in our home.
