The sensor worked well for about 4 months, but has stopped working entirely now. I have tried disassembling the control box and disconnecting the batteries to reset everything (many times). In fact the entire Mighty mule system has been a disaster since installing it. The control box has to be disassembled once or twice a week to re-adjust the gate closure or to re-set the unit so it will start working again. My family and i have been trapped inside our gate more times than we can count. Do yourself a favor and invest in a different brand. Mighty Mule has been a nightmare for us.

    Don't waste your money
    I followed the instructions and am pretty handy and couldn't get it to work properly. When I first installed it would work only during the daytime for some reason and now it doesn't work at all! Don't waste $175 and 2 hours.

      good product
      The gate opener serves it purpose to keep people out and to control who comes on our property. The gate is very slow to open and slow to close, which sometimes allows our dogs to get out. Wish we could change the timing to get it to close faster. Overall, a great product. We would purchase it again
