    Very easy to get this security system installed. I love that I can use my phone and know when someone has triggered a sensor while I am away from home. My house was broke into and now I feel secure again. Even while you are home, the sensor is triggered immediately when a door opens. I now have no more sleepiness nights worried about an intruder entering my house.

    My wife and I purchased the iSmart Alarm system as a deal of the day a while back and have been very pleased with the functionality of the system. We stopped into BB one day and I was showing her some of the automated front door technology out there and was pleasantly surprised to see that the alarm systems and additional sensors were now being carried in the store. I snatched these up and was able to put a "watch" on our entry to the house from the garage. We have one extra, which I will put on the actual garage door itself. The only way into the house without a chime is through the chimney!!!

    If you're like me and don't want to spend an arm and a leg every year or month on an installed home security system, this is a great alternative. It is extendable and the app is simplistic and easy to use. The contact sensors can be set to make noise whenever they are moved, which is great for keeping an eye on the kids or anyone in the house too. It sends automatic notifications to your phone, email, and whatever else you can think of. Really nice system.

    The sensor is very easy to install, may be a little bit bulky and if you don't have a withe color window frame it will be easy to identify

    Added another two sensors to doors and didn't have any problems adding them to the ismartalarm system. Wish the noise the sensors made was louder, but it's not too bad.

    iSmartAlarm - Wireless Contact Sensors

    Extremely easy to put up and to connect. I did find out that attaching the sensor to a metal door drains the battery usually within twenty-four hours. I had to put a rubber layer between the sensor and the door.

    The kit is very easy to install and to connect to the main kit. The only problem that I have is that the kit does not contact authorities. It makes sense I suppose since it says no contracts or anything. I feel like for $300 plus dollars to arm my home, if someone breaks in, I am left with contacted police myself. I am usually home alone, so I don't think that this is what I was looking for exactly.

    iSmartAlarm - impressive

    These window and door sensors work great. Unlike my previous system, these have a heavy duty magnet that allow a greater space between the sensor and the magnetic switch (3/4"), thus, preventing false alarms. The system also had a greater distance for the sensors back to the Cube. My old system I didn't have coverage to the basement. These sensors are sleeker and smaller than my older ones. They were very easy to set up and install. It's nice that they come with their own custom size backing tape. I ordered extra sensors to cover additional doors. I wanted to buy more,but due to the price, I thought that I'd wait to see how these worked out. I'll probably be ordering more in awhile. Overall, I'm very impressed with the iSmartAlarm system.

    These sensors are a must for the iSmart Alarm system. I wish they made packs larger than 2. You need quite a few of them to be fully covered. Great product.

    Added a few extra contacts to an iSmart alarm system I just installed. Very easy to install. I was concerned about how well the double stick tape would hold but seems to work fine.

    We purchased a couple of additional sensors because the original product only came with two. They were easy to set up and use, but overpriced.

    Super easy to install and works as it should. My only issue with it is that it uses an adhesive to stick to the surface. Putting it on is easy but taking it off and putting it somewhere else is not. Would have given it 5 stars if there was some innovation used for re-sticking it to surfaces after you decide you want the sensor somewhere else.

    I bought this system for my co-op and it has been amazing. It's great that I can set it when I go on vacation and shut it off from my phone when I have people come over to check on my place. Also love the home feature which disables the motion detector for when you're still home.

    This accessory for the DIY security system looks like it would work for some smart phones, but unfortunately not for our Android. We had to return it and the system for that reason. I would recommend this for someone who does NOT use an Android phone.
