Customer Reviews

I ordered the Mighty Mule Wireless Driveway Alarm model 231 because I have had fairly bad results with IR motion detector based alarms. The MM Alarm arrived on time and in very good condition. Right away after opening the box, I noticed there was a problem. The PVC pipe for mounting the transmitter has been cut on an angle to allow easier driving into the ground like a stake. Unfortunately, the wire to the detector also has to be run up that PVC to the transmitter, so you will surely damage the wire while driving the stake if your ground is not extremely soft. My solution was to drill a hole in the stake about about 10 inches up so that the stake can be driven and then the wire fed into the hole and up the tube to the transmitter. This worked and I was able to install the sensor and transmitter with no other issues. Next, I found that the advertised 400' range is very suspect. I placed the transmitter a little over 325 feet from my house and the receiver would not pick up the signal from inside the house. I had to take it outside where it worked well. I moved the transmitter to about 150' from my house and it works excellent. I would say that this alarm is not satisfactory at 400' and MM should advertise it for 250' or less to be completely truthful. If you want a longer distance model, you'll need to buy a different product. It would also help if the volume could be doubled. It seems that none of these alarms include satisfactory volume for those of us who are slightly hearing impaired.

My wife purchased the Mighty Mule FM231 wireless driveway Alarm and installed it herself. The receiver had a lose connection and sometimes it worked and sometimes it didn't. She called the 800 number within a couple of days they sent another complete system. She just took out the new receiver, replaced it with the old one sent the system back to the company as damaged. Now our system works great no false alarms from animals or children. We Love it
