Customer Reviews

Heavy Duty Single Swing Automatic Driveway Gate Opener is rated 4.1 out of 5 by 81.
Rated 1 out of 5 by from Mighty Mule Garbage! on my fourth gate opener in last 6 years. they last just beyond warranty. 1st was the control board which cost like two hundred! cheaper just to buy new one. 2nd and 3rd was the arm itself that went bad. It was the Chinese electronic boards that go bad. One was under warranty but wanted me to pay for shipping. how much to ship an arm? An arm and a leg since it is 4 feet long. 6 years ago had a great experience with technical support. Now they just want to sell parts. The only reason I continue with this sellout company (China) is because I bought the Home Depot warranty. I need to go into business making these arms and stick to the way things used to be. Manufacture a product as if it is going on my own family home! They don't have any competition that is the only reason they are in business. Sorry for this long post but am tired of dealing with this. Note my gate has been on solar so I don't want to hear lightening hit it any more!

Rated 1 out of 5 by from The MIghty Mule Openers Fail Frequently We have had the heavy and medium duty gates replaced three going on four times. They last a few months or a year then they stop randomly stop functioning. Their support department is overwhelmed. Expect to call 6 plus times to get a person. They are not reliable.

Rated 3 out of 5 by from Good value, good design, not very reliable or long lasting Let's start with the good: the price and the availability at Home Depot. The kit had everything I would need for standard hookup. There are lots of accessories available from the manufacturer as well. Cool. Not so nice: the battery had been sitting around on the shelf too long, so although "new" it (1) wouldn't take a charge and (2) zapped the circuit board. I call up the manufacturer and they say "you abused the unit, no warranty coverage." After an hour of yelling they decide to actually cover it, replacing both the battery and the circuit board. OK fine. Battery does not last very long: first one got weak after maybe 16 months, next one leaked acid after about 3 months. They DO say "replace very 2 years", but that's optimistic and the batteries are $50 each after you've paid for shipping and taxes. The actual motor drive then died after 19 months of once-a-day use. Perfect timing!! Self-destructed due to mechanical failure just after end of warranty period. Replacement part is 2/3 the price of a whole new I just get a whole new one and have lots of spare parts.

Rated 5 out of 5 by from Mighty Mule 500 gate opener The Mighty Mule 500 gate opener seems very heavy duty and installed easily on a 16' tubular steel gate, with excellent instructions. Just installed so the above scores are "so far", and are partially due to my comparison with another brand we had that had many problems from day one and lasted about 2 years with several periods of down time [bad circuit boards]. The Mighty Mule operated flawlessly the first operation. The unit's operation is quite a bit noisier then the old one but it has an 18 month warranty so not to worry.

Rated 1 out of 5 by from Junk, junk, junk Going on my third GTO product in three years. Originally had the GTO2000XL Pro gate opener and it failed on me multiple time. Was tired of messing with it so I thought I would try a different version - the Might Mule 500. Guess what, they're pretty much the same thing. Junk. Sure the circuit board is easy to understand, sure its easy to mount the control box, hang the arm, etc. The only problem is at the end of the day, its junk. I've send the entire arm and control box back to GTO twice in 9 months, yeah, opening my gate manually is a pain. Having to do this for 3 weeks each time while GTO "fixes" the problem is a bigger pain. Did I mention I had to find a box big enough to house everything (made the mistake of throwing original box away) and pay for shipping each time. Good luck.

Rated 4 out of 5 by from Good product, some what easy install. After installing the opener and lock,going through several trial and error tests, re-engineering my12' aluminum farm gate and beefing it up, I LOVE IT! No more stepping in the mud when it rains! And the security knowing my horses will not be running down the highway after someone leaves the pasture gate open is a weigt off my shoulders! Will give an update after a few rain storms and time. FYI 5 watt solar panel seems plenty for residential single gate

Rated 5 out of 5 by from This is an excellent product. It's kind of difficult to install. My husband & I are "experienced do-it-yourselfers" and it took us 5+ hours on Saturday and about 7 hours on Sunday to completely install the opener and the lock. But overall, you can do it yourself. We got it done and we love it. The lock is wonderful. Definitely a time saver

Rated 3 out of 5 by from Replacement gate opener Original gate opener was caught by the heavy winds and the opening rod bent and rendered the opener useless. Hopefully, the new arm will not suffer the same fate. Package arrived promptly and well packaged. Arm installed easily and is working well at the moment.
