    We've had this installed for about a year now. Easy install (though one door/window sensor was tricky). It's been reliable and works fairly well. The kit had base, motion sensors, door/window sensors, fire alarm, & panic button. We added more sensors and a second keypad for the back door. Sometimes status changes don't reach the backdoor keypad when its batteries are low. One complaint we have is that monthly monitoring of ~$25 is required to use the phone app (Monitoring w/o app access is ~$15). But considering what the phone app does, we think the monthly cost should be lower. But over all it gives us peace of mind.

    Make sure you check cell coverage with T-MOBILE before you order. If no T-MOBILE coverage, check Verizon (they have a Verizon module but you must call company directly to get that). If no Verizon coverage you need a land line for monitoring. Also the $14 or so monitoring fee they quote is a BASE package. If you want text and email alerts it's about $21. That is not easily found in disclosures. Monitoring is EXCELLENT with very fast call response. No contract required.

    It was the easiest thing I've installed all year and maybe this decade. Really, efficient and well worth the money. I am shutting down my ADT System and making the switch. How can I not, when it's proven to be Owesome!

    I have been hearing commercials on the radio regarding Simplisafe Home Security Systems. I have actually researched them online previously as well. I was extremely happy to see that Best Buy now carries them! Set up is so easy & I am happy my home is secure.

    I absolutely love this system. I had some trouble when I was hooking it up because they come standard with a T-Mobil card. Unfortunately, it did not work in my area. Customer service was awesome and had a Verizon card out to me in 2 days. If you are even considering it, get it. My wife sleeps so much better now when I am out of town. And the great part is I receive txt alerts when I"m gone so I know they are all safe and sound.

    This is by far the best alarm panel installation I have had ever! It works right out of the box without having to do any complex pairing or programming. The USB stick that comes with it allowed me to do all the programming from my laptop as I setup the devices around the house. Once I was done, it loaded the programming onto the usb key, then I just stick it into the home base. It automatically downloaded and presto, I was up and running. This is so simple anyone having a massive blonde moment could still figure it out.

    I set off the alarm by mistake, while letting the dog out. I quickly realized my mistake and called the monitoring company to stop the response. By the time I hung up the phone I had a police officer at my front door. This system works like a champ and I get a discount on my home owners insurance for installing it.

    This really is a great product, there are lots of features and you can order more components that are not included in the package such as window break sensors. I was able to install and test each component in about 30 min. Activation and getting the app squared away took about another 30 min. It works very well.

    Love that there is no charge (unless you choose) to have this security system to protect the home. It is very east to set up and install. Took about 20-30 minutes in total.

    This security system literally only took me 15 mins to set up and was working very quickly (no ADT hassle). Also it is very easy to order more sensors from their website and add it to your home security system. Overall security wise it is just as good as other systems (if not better due to their cellular hub) but costs around half the price, and the customer support is pretty good. Only issue is that the sensors are a little bigger than other companies and don't look that great (but thats not a big deal :)

    After months of research I decided on Simplisafe. Extremely happy with the system. Works just as advertised. Feeling safer than I have in years. I had an issue with the tower in setup. Called support and they determined I had a bad phone card. They shipped me another one with the directions to install it in my tower. Computer setup was super easy and phone ap works great. I did find that the sticky pads on the motion sensors does not work if you plan on hanging it in a corner, but some very tiny screws are included. The only complaint is that when I come home in the dark I cannot see the numbers on the keypad. It does not light up until the code is entered. I knew about this tho from previous reviews. i just keep a tiny flashlight near the keypads. I did add and extra keypad by the back door. My dog sometimes needs to go out in the middle of the night. Again I can't see numbers in the dark so i keep a flashlight near that keypad too. Overall I am extremely happy with this system and have already added an extra keypad, motion detector and keychain. Love being able to add extras when I want. Lightening fast calls when system is in test and alarm mode. When you register you are given a free month of monitoring and they threw in another month when I had to wait for a sim card replacement. So for now I have full service with text messages and calls. I may cut back later to 14.99, but for now 24.99 is a great price for the full service while I am still learning. I can to arm and disarm from anywhere.

    This system is well designed, adaptable, easy to manage, quick and easy to install, technologically savvy, and I can't imagine using a different system. It took 15 min to set up, no tools, very simple! It has its own battery that lists forever, and communicates to monitoring station with its own cell service. It works if the house has no power, if the internet is down, it's independent of the house! I am notified about alarms, any system problems on my phone. The battery was low on the smoke detector and my phone alerted me. We have as small dog but no false alarms. It's sensitive for movement otherwise, has standard door/window sensors, motion sensor, glass break sensor, added the camera which works very well... And automatically turns on when there is an event, even when someone comes home! It records these events. If watched the recording after alerted that system was turned off to make sure who it was, and who they were with. I can't recommended this any higher. Simply excellent.

    Dead easy to install and the web page interface makes it really easy to customize. The text alerts work absolutely seamlessly and I really appreciate knowing exactly what's going on at home in my absence. Such an improvement over the technology of the flaky alarm system I put up with for years.
