To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I installed my Simplisafe system a couple of years ago, and swear by it. I've had no problems with it, the sales staff is top notch, and the technical staff is amazing. This Panic Button is the 2nd one I've installed, and took me about a minute. The Panic Button is a necessary accessory, and one that you hope you never have to use, but it's comfortable knowing that it's there just in case you DO need it. Like all Simplisafe parts you can run occasional testing to make sure everything works. Simplisafe is what it's name implies: Simple and Safe!
After purchasing system and downloading app, I contacted them as my app was not working. After all the money spent beforehand, they advised me that the phone app cannot be used unless I purchased the monitoring service.
