The only "hidden" fee with Simplisafe is when your smoke alarm falls off the ceiling and activates some kind of test while you are out and the system calls the wrong number (your wife instead of you) to check and she doesn't answer then a dude physically calls round to check everything's OK then they charge you £120 for the callout.
Fit your sensors properly and answer your phone when they call to check everything's OK. And remember your safeword or they either won't get off the phone or they'll send someone round.
Ours wasn't that, and trying to remember what it actually was at 2am the only other time they called(when the other smoke alarm fell off the ceiling - I'm clearly shit at mounting smoke alarms), was not condusive for getting back to sleep.
