Review: Works with Simply Safe systems that lose sensor signal. - Had issues with losing signal from exit sensors of Simply Safe security system. Large house and a lot of electronic signals around - WiFi, phone etc. Had repeated issues with having to reset or reinitiate connections with sensors, exit sensors in particular. Solutions on-line mostly had to do with extending internal antenna's which permanently modified the sensors. Tried this device, placing it in a central area between the base station and most remote sensors. Has reduced instances of lost signal by more than 95%, maybe more like 99%. Just plugged in with no modifications. Boosts all signals at 433 mhz. Clean simple solution.
