Does anyone have any experience with Simply Safe home security? I've been toying with the idea of a home security system for some time; our room is upstairs so I don't trust myself to hear/wake up during a home entry. Plus it will give me a little more peace of mind when I leave my wife and child at home during business trips. Looks like a pretty good deal, with straightforward installation and low cost. Eveything is wireless, and it uses a GSM network so nobody can cut the line. Of course I imagine that also means a lot of battery changing... It has me tempted, but I'm a little afraid of getting what I pay for... Edit: Apparently Google searches are more effective when you get the name right. It's called SimpliSafe.
