I've had a SimpliSafe system for about a year and a half. The system was very affordable, customizable and easy to install. The equipment is sturdy but not particularly attractive. It's a matte finish white plastic that is difficult to clean. After about a year the keypad looked like I'd buried it in the yard, dug it up and remounted it. The base station is fairly large, looks like a prop from the original StarTrek and is quite persnickity about where you place it. The entry sensors fit fine on doors but are too large to fit on my casement windows with the screens installed, so I can't open my windows on a nice day unless I want to spend the evening catching flies. The components seem to work fine, though, except for the keypad which goes through batteries faster than any ten flashlights I've ever owned. It's supposed to let you know when the batteries are getting low, and it does get around to that, eventually. While it's warming up to the idea, it just stops communicating in any useful or consistent way with the base station. I discovered this after I triggered several false alarms even though I was pretty certain I'd disarmed the system. Concerned that I might have early dementia, I started paying particularly close attention and discovered that although the keypad displayed "alarm off", the blue light on the base station was frequently still on indicating that the system was armed. A couple days later the keypad finally displayed a "low battery" message. This scenario repeated itself again a few months later. I've learned over time that as long as I keep the keypad fed regularly it doesn't bite. The monitoring service has been the bright spot so far. They're very attentive and polite when they call. (A word of advice - don't test your smoke and CO detectors consecutively; mix them up with your other sensor tests or use your cell phone as the primary contact number. The monitoring service calls you after each smoke and CO detector test to let you know it passed. I almost had a heart attack climbing up and down the ladder and running up and down the stairs to answer my land line.) The worst part of my experience has been the customer service, or lack of it. My purchase experience was relatively good. Although the sales technician misquoted the cost of my system, the customer service representative honored the quoted price and offered one month of free monitoring to compensate for my inconvenience. However, since purchase, my experience with customer service has been far less impressive. During my journey of discovery with the keypad, I made numerous attempts to call the customer service support line during their stated regular business hours. No answer. Not once. On two occasions, I left the phone ringing on "speaker" while I did other things - cooked and ate dinner once, cleaned the entire house the second time. No answer. Not once. You get what you pay for.
