Mighty Mule FM231 Wireless Driveway Alarm is rated 4.4 out of 5 by 19.
Rated 4 out of 5 by from This is my second driveway alarm from Mighty Mule. Once installed they work pretty good. Do need a choice of getting one with a longer cable as the one supplied is kinda short for some installations. The only thing I dislike about it is, I CAN'T HEAR the alarm if in another room even when turned to loudest setting! Product would be 5 stars if it had a LOUDER sound which could be adjusted to the user's preference.

Rated 5 out of 5 by from Driveway alarm Driveway alarm is great. I think you need a louder sound for it. I have mine turned up all the way and you need to be sitting next to it to hear it. Just thought you might like to know.

Rated 5 out of 5 by from alerts every time with no false alarms installed almost a year ago because we can not see the driveway from our back patio. its a little work to install but definitely adds a level of security to a long driveway.

Rated 4 out of 5 by from False alarms after 2 years of service As the title says, false alarms.after a year of service. After doing all the common sense checks and troubleshooting I discovered that the alarms were temperature related. I did not need the coil connected to set it off. While holding it in my hand I could set it off with the heat from a hair dryer. Bottom line after taking it apart, I discover that capacitor C4 (.47uf) on the board, was the heat sensitive part. I replaced C4 and it has been working fine. The only thing I can think of is that you got a bad batch of capacitors.
