The best system for DIY
I’ve had my SimpliSafe system for about two years now, and recently decided to protect a third door, so I bought the sensor. I am highly impressed with the entire SIMPLISAFE lineup, as they are great quality at reasonable prices and provide excellent protection. I highly recommend getting either of the two monitoring services for complete protection. I personally have the $25 a month plan since it gives me so much more options. ADT wanted almost $40 a month for virtually the same coverage

SimpliSafe security system.
I’ve been using SimpliSafe for well over 15 years. It’s an excellent product and from time to time sensorsdo go bad and need to be replaced but not too often. I have a pretty large system so that’s to be expected. It’s awesome and Sensors work extremely well. And highly recommend Simpli Safe for their home or business.

Great bang for your buck!
These Simpsafe sensors worked exactly as described for my security system and at a fraction of the cost. I will do business again if I need additional sensors.

Missing one of the mounting brackets, but I had a spare so it's fine. No mounting tape and batteries were already installed, so not new.

working as expected
working as expected, a little expensive as you can purchase from Simplisafe for the same price, but since others are scalping this item on ebay, this was a reasonable deal
