Hi guys just want to give a heads up on these window/door sensors. The last 4 I ordered were defective and repeatedly gave false alarms, x10 is practically giving these things away and I think they have let quality slip, if that's possible. I use to say how dependable these door/window sensors were but not any more! It's a good thing I tested these pryer to putting them in the system. I'm still a few months away from finishing my DSC super system this thing is going to be expensive but I'm buying the best so I fell it's worth it. X10 should really pay closer attention to quality on their security equipment I mean if a light doesn't come on that's one thing but this stuff is supposedly protecting your valuables and possibly your family and you want it to be something you can depend on, I mean you could be at work or out of town for that matter. I don't know if this is due to shoddy quality sloppy workmanship or that they are just trying to cut corners but I find this really disturbing and felt the folks that frequent this forum and new buyers should be made aware of it. Hopefully x10 will quickly address this issue and correct this.
