I've been using this system since 2005 and really like it. Though I've learned some things the hard way, like not mounting the wireless sensor directly to a metal surface, I really like the system. It has already saved my house/possessions once. I like it enough to be looking for another two wireless remotes. If anyone has one or more, please email me at jlauren@myadvantageplus.com. Also if anyone else is still using the system and needs some remote sensors, email me. I have a few extra. DIY Jerry
