siren looks good, works good, and is easy to install. what else could you want?

works great! i can see it a mile away!

it is loud, you could hear it along ways away. very easy to install. i also like the tamper feature it has.

they work perfectly and make me feel much more comfortable while i am away.

i had a problem with this sensor because my doors are very tight. the sensor would get stuck and not go off reliably. it also put a small groove in the top of door. i am switching to the magnet sensor.

works perfectly! i used it in the mud room that has no heat or air conditioning with no problem.

they work exactly as intended. i have not had any issue with the 4 i am using.

Works great, price is great, it is easy to use.

Great system!

This kit offered exactly what my wife and I wanted in the ability to arm and disarm our system remotely. The installation was simple and the support from Sterling was terrific. He walked me through each step of the programing. I had to end the initial call before we were done and he told me when he would call back and to my suprise he did!
AlarmGrid get's an "A" in my book and Sterling "A+". He is what "Good Customer Service" is all about and AlarmGrid should be happy they have him.
