Once I received the MM572, I was able to install it in a day. Directions were clear and I only had one problem. I was able to call Tech Support and they walked me thru it right away. I had MM previously and wanted to stay with a known product..... I'm hoping to get 10 years out of this one as well.

I'm updating this review on January 2021, one year from my original purchase. My rating of this item went from 5 stars, to 1 star, and now is at 4 stars. Originally, I was very pleased with the functioning of this gate opener. Nine months later, The opener stopped working. Mighty Mule instructed me in testing the circuit board and concluded that the circuit board was not operative and needed to be returned.
I was sent a return authorization form. After mailing back the circuit board I heard nothing, and had to call them which entailed being on hold for a long time and getting transferred. But, Mighty Mule ended up being willing to send me a replacement board. The problem was that the board was not available and might not be for 4 months.

After 2 months, and one more call to them, Mighty Mule bent over backwards to ensure that I received the parts I needed (& even some I didn't need.) So, while the gate opener is now working fine, and I love it, I'm subtracting one star for the very disorganized process of customer service, including: long hold times, Emails being sent which can't be responded to, and confusing forms with wrong contact information. But, because, in all likelihood, Covid affected their supply chain and they really tried to provide what I needed I am again a satisfied customer. Here's my original review written in February 2020.

I installed this 6 weeks ago. This is a brand new model, so there are very few reviews. I wanted a heavy duty opener, because I've seen a number of inoperable light duty openers hanging uselessly on neighbor's gates. I've been very happy with it. Having electricity at my gate already, this was perfect because it isn't bundled with a solar panel, and has a small 12 volt battery supplied. (There is room in the control box to add a second small 12 volt battery.) Customer support is ok, but, I believe the support person is reading from a script. The support for the separately purchased remote controls was excellent. I bought two key panels (FM 137) and 2 extra remote buttons (FM 135). Because the remote buttons (FM 135) are older technology with switches, and Mighty Mule doesn't explain the details in their manuals, I needed guidance. The technical support guided me through programming the buttons so that the gate can't be opened by just anyone with a mighty mule remote. I will try to remember to revisit this review in a year and update if it is still working perfectly. But, at this point, it is 100% reliable.

Easy to install and number you can call if you have problems !
Love it

I just had a very frustrating talk with a tech support guy at MM. I am installing a MM571W gate opener and was surprised to find the included battery loom which is designed to link 1 or 2 batteries to the control board, had a fuse in the +lead to only one battery, I'd have thought either a fuse in each battery's + lead, or just one but in the + cable to the control board would make more sense.
After a long wait on hold, I explained my concern to the rep, who told me, don't worry the fuse is just there to indicate the health of the battery! I tried to explain, that that is just not true, a fuse is a device designed to break a circuit if too much current is flowing.
In the end I told him he shouldn't be doing tech support and put the phone down. If anyone from Mighty Mule reads this I'd appreciate a response. Thanks.

One of the actuators failed. Warranty was breeze. thank you.
