Rated 4 out of 5 by 8 reviewers.
Rated 4 out of 5 by Great for the price My wife loves not having to get out of the car when by herself, and my 10 year old son (who used to be the automatic gate opener) gives it an "excellent" rating! It took me a few hours to install but I'm slow. We have been using it for months and it is fantastic. It is pretty slow but the trick is to push the button far enough away that you don't have to wait too long. Our cars have the programmable button in the visor or overhead console which means we don't have to use the supplied clickers which we gave to one of our daughters, keep one by the front porch, and one by the back porch for when we go out to get the mail. The push button works from the house which is about 75 yards from the gate so if a guest arrives or we forgot to close it at night when we go to bed we can activate it from the house! We got the kit with wireless keypad which works great, and 3 remotes. No complaints yet! August 13, 2013
Rated 4 out of 5 by DKlein Had a few problems with the remotes, getting them to all be in sync. One did not work, but I called customer service and they replaced it without any problems. I would recommend this product to others. August 24, 2011
Rated 4 out of 5 by Works great I'm pleased with this gate opener. It is simple to install by anyone with some mechanical and light construction skills. Keep in mind that this opener will require the addition of a battery and a weatherproof box to put the battery in. December 11, 2012
Rated 4 out of 5 by As advertised We purchased several Mighty Mule products with the FM350 combo being one of them. Everything was as advertised and was received promptly. December 18, 2012
Rated 5 out of 5 by Works great This is our second mighty mule product. Since we've been very happy with the driveway alarm, we were not hesitant about purchasing another product. Installation was made pretty easy by having written instructions and the DVD. It does take two people and a little time but well worth it. We installed a 12' chain link gate and it opens smoothly without any strain whatsoever. No more getting in and out of the vehicle to open the gate for us. We also feel much more secure.
