The batteries in the door sensors drain like crazy, and I'm using good Energizer batteries.

I originally gave this a lot of stars, but 9 months later ALL the batteries are dead

If they made use of a decent battery that lasted it might be a decent system but this is the pits.

And everything except for the panic button worked (the battery in the panic button apparently exploded and ceased to function which indicates these products might be sitting on the shelves a bit too long...) very well

Replacing the hard to find batteries cause the electronics to fall on the floor, so I am down one sensor.

So, the contact we thought was bad, only had a loose battery.

I replaced battery and still did not work

Soon I found that the expensive batteries I installed were dying too quickly

Poor battery life, Batteries for the window units may last 6-9 months

He saw the battery was loose.

I soon realized that the batteries were dying too quickly and i thought that the batteries I was using were bad

, so it looks like the original battery had got too low

only drawback is the batteries in the motion

I did have one of the door/window sensors come with a defective battery and probably the sensor being defective as well

This is important as a low battery will trigger false alarms when the system is armed

It works as it should so far.

Seems to work as it should but at least 2 of the batteries in the door/window contacts were dead upon arrival

The system works as it should.

The electronic parts are pretty durable ,as I have found out, as they fall to the ground and almost instantly disassemble from the impact

I did some thorough testing on all the components and they all worked as they were supposed to, and I haven't had any false alarms

After receiving it and setting it up, I found that it recommended T-Mobile, alarm sim, or AT&T, and chose T-Mobile for the price ($15 for 30 minutes, good for 30 days)

B & E's in my neighborhood prompted my purchase.
