Plus, the window and door attachments fall off too easily.

I personally added 2 more door/window sensors, smoke alarm and 3 more sirens.

They include two large generic window stickers that don't even tout the company name.

The window and door alarm contacts are weak plastic pieces that break easily.

Glad to have the heat/motion sensors because if a window is shattered and stepped through, the sensors on the windows/sliders will not go off.

we absolutely love this item it gives us peace of mind security and we go to bed now and get a good nights sleep without having to worry about anybody break in and without us not know yet thank you very very much I'm going to order more window and or alarms in the future thank you

I all ready bought two systems from this seller

All the sensors worked and the alarm is easy o programe.
