I bought one of these a few months ago and am really very impressed. Can't say the distance from the sensor to the base is 400ft, but for the price it's good. I wasn't aware that deer and bears roam the property until we were introduced to them several times. It's amazingly durable. I'm at the beach and we have good squalls hitting like crazy. Many times a block I just sat on the surface has blown out halfway to the driveway, but damn I was able to put it back on and it worked like a champ. Biggest minus point: The cables that lead to the battery in the sensor are tiny and don't have to be torn off much. 9V batteries are pretty powerful so you have to be careful. In fact, I'm replacing mine with a new one that I promise to install this time due to wiring issues. The next major downside is that it's southwest facing, the setting sun will light this thing up until you have to turn it off until the sun goes down further. and hopefully remember to activate it later! Biggest plus: of course the price. The battery lasts a long time and the absence of a red light on the sensor lets you know when it's low. It is very loud when calling even at low volume. I was able to install the sensor in my driveway about 200 feet from my house and I could hear it ringing. I am currently looking for a long range unit as my driveway is VERY long but this unit was great for the price. There are no settings or settings, just pop in the batteries and you're done.
