Easy to add to our current system. Worked well to expand and use for doors and windows. Price point was same as direct buy from simply safe but faster shipment with prime.

I updated to the SS3 in 2018 and have been using these sensors every since. I easily get 5 - 7 years out of these sensors. They are very easy to set up and pair with your base station. Depending on your security settings, the sensors will notify the base station when a door is open (with the alarm off) and a tone will let you know if door has been opened and of course if the alarm is set, you will get an audible alarm from your security system. If by chance, you do have an issue with the sensor, just call SimpliSafe and they will replace it. Highly Recommend
