Mighty Mule FM231 Wireless Driveway Alarm is rated 4.5 out of 5 by 17.
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 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 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 Dependable, Reliable and simple to install I've had ours for years, (300 foot drive) when friends are over and hear it work and hear about it from me they go out and buy one for themselves. Well done instructions come with it. Worth the price, it works great!
