Title: Very Poor Range
Review: I had one of these and returned it. I set it up about 700 feet from my house and it wouldn't go off. They say the range is 900 feet. I removed the sensor and walked toward the house stopping every few feet and setting off the sensor with my hand while my wife listened for the alarm. I know the sensor went off because the green light on the sensor flashed. I had to get within 30 feet of the window where the base station was before the alarm would go off. This was with brand new batteries in the remote unit. My house has wooden studs and wooden window frames so it wasn't metal blocking the signal. I'm sorry but it just didn't work for me.
