Rated 1 out of 5 by from None I have bought 3 of the Mighty Mule 500 in the last 4 years and now I will never ever buy another Mighty Mule again. I am going to pay the extra money and get the Apollo brand. Its time to try something else

Rated 5 out of 5 by from The new circuit board is easy to understand. This circuit board is user friendly. No need for a separate board for the lock. No need to flip switches for the auto close duration. Easy to read.
