Reliable, Easy install
Easy install, extremely easy setup when using Mighty Mule opener. I replaced a different brand that was indiscriminately shorting my closing circuit out. I chose this brand and style because I have one on the other side of the gate that has been in service 15 years with no problems.

Great instructions, unit worked perfectly
The keypad on our gate failed. It was 16 years old and had been flawless until now. I was able to get this delivered the next day. Took me maybe 15 minutes to cut it out of the blister package, read the directions and install it in place of our old keypad. This one said Mighty Mule and our old keypad said GTO on the front. I found on the reviews that someone else had asked the same question of whether it would work the same. It worked perfect with our Mighty Mule 360 gate opener. I'm very happy with the quality of the keypad. It feels solid and the keys have just the right amount of spring to make it feel as though you've depressed it hard enough.

Reliable, easy to program, and holds settings even when batteries die
These keypads work awesome! Setup was super easy, and I only have to replace the batteries about once a year, even with daily use. The best part? When the batteries die, you donโt lose your codes โ unlike some other keypads Iโve used before. That alone saves a ton of frustration. Itโs been dependable and hassle-free, exactly what you want in a gate keypad.

Works okay, but it needs updated, truthful instructions
As a product, the keypad is of good quality. Time will tell if it will last, hoping others can speak to that. There are no instructions in the box, only a QR code. Watching YouTube videos will be your best source on how to program the keypad. The main reason for my review is the incorrect instructions that can be found on the items page. It shows there are two terminals, one for input power and one for the contact closure. The truth is, it only has a terminal for the contact closure. I'm guessing the product has changed over the years, but those instructions should be updated.

Works great! No need for the intercom model, just put your phone number on it.
This wireless remote for my Mighty Mule gate opener was brain dead simple to mount and program. I had tried the one with the intercom but that failed miserably because it would not work line of site at less than 300 feet, plus the alarm was very obnoxious. This simple keypad does the job and I just put a small label on it "CALL 202-555-1212" (your number) so folks who arrive at the gate will use their phone to call and you then give them a code to enter or ask them to leave. It's also easy peasy to program up to 25 entry codes and you can even program temporary ones that will auto delete up to 9 days later. Installed lithium AA batteries (it takes 3 of them) so we'll see how long they last. I expect at least a year.

Works as expected, should have bought it sooner
Highly recommended. Just that "one time" that someone is at the gate and their remote doesn't work, or even for emergency access, this is a necessity. Installation was easy, operation is great. Mine was installed off to the side a little hidden so thieves dont see it.

Good brand
All this "Mighty Mule" stuff is sturdy and works well. I have fitted two double gate openers now and both are working perfectly after a few years in harsh winter conditions. Installation instructions are clear, remotes hold memory without loss. I recommend this brand.

Works great
Replaced a 15 yr old model. Key pad was worn out. This is a Factory original, works great with MM gate controller. Just not sure if the direct wiring will power the pad, would be nice if batteries were not required.
