Review: Great opener - Works great. Just be sure you BUY A NEW BATTERY, whether you think it is good or not. Ours was pretty new and we checked the cells, gate opener would not work,changed the battery and worked like a champ. It actually said in the instructions, to purchase a new battery.
Review: Great System, easy to install, works well. - Purchased this Mighty Mule Gate Operator, together with the 10w Solar panel (MF123), Battery Case and batteries (FM150), some extra remotes, and the wireless keypad and goose neck mounting post. Instructions were straightforward, and very understandable. I also used the "Bilt" app, which had some helpful tips beyond what was in the instructions. All in all, it took me far longer to design and fabricate the mounting for our 6-5/8" fence posts than it did to install the operator, controller and battery. Installation of those was easy, although digging a post hole for the remote keyboard post was a bear due to our soil (Adobe Clay, like concrete in the summer!). Everything works very well, the remote keyboard even has light up keys for night time operation. Pretty happy to not have to get out of he golf cart or truck every time I head down to the shop. Thanks Mighty Mule, was really pleased with your system.

## Questions & Answers

**Q: Why does my remote not open my gate for more than 20 feet away**
A: I had same issue, seems that little tiny antenna that comes with it is too small, I couldn't even get 20 feet. So, I added an extension cable and new antenna that is about 12 inches tall, I built a mounting bracket and added it to the top of the post where the control box is mounted. Now my remote works from inside my house (pointing out the window), which is about 300 feet from the gate.
These are the 2 items I bought, about $15 total from Amazon:
- WiFi Antenna Extension Cable SMA Male to SMA Female RF Connector Adapter RG316 2M
- TECHTOO 9dBi WiFi Antenna with SMA Male (SMA-Plug) Connector Compatible W/Anran Haloview IP Camera & Other Wireless Security Camera Antenna - 2.4Ghz Wireless Networking Device (SMA-Plug 1Pack)

**Q: I was told to buy two mm371w for my 2-panel gate. can the two remotes be synced so they work as one?**
A: The gate panel learns the remote.  I don’t see why 2 panels won’t learn one remote. 
Good luck.   I am pleased with the new changes upgrades to the  system.

**Q: Does this detect incoming objects?**
A: No

**Q: On the mm 371 does any one know how far the battery can be located away from the controll box also unit is solar charged.**
A: The wiring harness on the control to the battery is about 2 feet.  This would be as far as you could place the battery from the control box.  You can purchase a separate solar charger to connect to the gate opener, model FM123.

Works great. Just be sure you BUY A NEW BATTERY, whether you think it is good or not. Ours was pretty new and we checked the cells, gate opener would not work,changed the battery and worked like a champ. It actually said in the instructions, to purchase a new battery.

### ⭐⭐⭐⭐⭐ Great System, easy to install, works well.

### ⭐ DO NOT BUY THIS GARBAGE OPENER!! YOU WILL REGRET IT!!!
*by F***Y on March 27, 2023*

Over the past 17 year, I have purchased multiple Mighty Mule gate openers (the MM350 and later the MM360), as they only last about three years at most, due to a design flaw in the arm allowing moisture to accumulate and corrode the board within. After about two years, the latest arm died in September 2022 and I was dismayed to find that the MM360 model had been discontinued and the only similar replacement was this much more expensive MM371W. However, I was hopeful that the new design of having the control board in a separate weatherproof box might justify the additional expense and thereby give the arm a longer lifespan. This opener began giving off an error code beep indicating that the battery was low, after only a month of use. After verifying that the wiring was properly connected, I assumed the battery to be the problem and took it to the auto parts store where I had purchased it and their testing revealed it to be fine. I returned home and confirmed the solar charger was working fine, but the design of the MM371W requires the charger to be fed into the board, rather than connected directly to the battery, and when I tested it, I found no charge coming from the board. In the midst of my second Mighty Mule gate opener failure within a month and a half, I called the toll-free number provided in the installation manual and was on hold for over 20 minutes when a representative finally connected, then was promptly hung up on. I immediately called back and was thankfully on hold for less time, and after explaining to the service representative the results of my testing, I was asked when and where I had purchased the opener, to which I told them from Amazon about a month prior. The representative advised rather than sending the opener to Mighty Mule to be repaired, I return it to Amazon, which they graciously approved, even though it had been just outside of the 30-day return period. Upon initiating the return, I immediately purchased another MM371W from Amazon, installed it and it has been working fine up until just last week when it has begun emitting an error code beep for a low battery after use. Naturally, I tested all of the connections and found everything to be as it should, and noted that the beeping is not consistent in frequency or duration. However, I has begun to occur more and more the past several days and I am now to the point to where I have to deal with YET ANOTHER defective Mighty Mule gate opener. And I just now clicked on the link for product support on this item's page and the link to "visit support website" takes you to an entirely different manufacturer! SOMETHING THAT COSTS THIS MUCH SHOULD OPERATE PROPERLY AND NOT INCONVENIENCE ME SO MUCH IN TIME AND FRUSTRATION IN TRYING TO REPAIR AND/OR REPLACE IT!!!!!!
