Mighty Mule FM350 Automatic Gate Opener is rated 4.3 out of 5 by 18.
Rated 4 out of 5 by from I am very happy with the over all result of my new mighty mule gate opener. I bought the mighty mule350 because it could either push to open or pull to open. I required the push to open but the push to open bracket needed to make it functional was not included. I had to order it separately if you check my paper work. Extra time, money and effort that I didn't count on. I now have a gate that is great but i believe that this bracket should have been included in the assembly provided. Please review your packaging details to see if this could be done. I'm sure it would save people time and avoid confusion. There was no mention of this being needed in the advertisement,but after watching the video again I spotted the brief statement that this part was needed.
