Rated 5 out of 5 by from Efficient-Fast-Less Expensive than Costco My Mighthy Mule FM500 died a sudden death, unexpectedly. I needed a replacement. Bought the whole gate opener which is just a little more expensive than the control box alone. Disassembled the box and the electronic board and replaced into the old one and in about one hour with the help of my wife we installed it and works again perfectly. Now I have a extra opener.

Rated 5 out of 5 by from Excellent Gate Opener This is the 2nd one I have had in 20 years. You won't be sorry. Keeps unwanted guests and sales people out. I have the dual model and it works great. You must get Automatic Gate lock with this dual opener. People will try to seperate two gates to slide through. Great unit "Outstanding"
