Comments

Rocknrotty: Good product have had these installed for 3 years work at -30C. Pretty hard to get to work properly. Not for a novice installer. Mounts loosen over time once a year. ended up welding all brackets once aligned and working properly.

somberserker: The installation instructions are clear and installation is not hard. During the summer they work great. The reception on the unit when using the remote openers is a little weak because sometimes it takes several presses on the remote to work. However, I'm now heading into my third winter with these and they stop working when the temperature gets somewhere below 0. I suspect that there is some problem with our units because we have neighbours with the exact same openers and they have no problems. So maybe you get lucky and maybe you don't - pretty expensive gamble. Considering we have below zero weather for a good portion of the year I can't give a good rating.

MeusesMom: Purchased in 2014, has been in service ever since. Used mutliple times daily, as we go in and out a lot.
Live in Oregon, and having to get out of the car in the rain/cold to open the gate is now in the distant pass..
Bought extra remotes for all vehicles.
A real workhorse, this opener set has been problem free since purchased here, and put into immediate use.
Set up takes some customization in most cases, so get a few friends with good heads together, with a few basic tools, and you'll will be installed in short order.
WE LOVE THIS.
IF and When it dies we will buy another.!
All Stars for awesomeness.
------------------ UPDATE 3.12. 20 -----------------
Have used it frequently every day since purchase, and it still works great!
WE LOVE IT.

John & Lin: do not waste any of your money on anything else. get this brand. Trust me. that other junk stressed me out! hand to send back with all of that stress. when you get this take the laptop to the gate , bring up youtube and watch, pause watch pause take your time get a beer, coffee, soda, take a break go play the dog a little. next thing you know you are done, and it works great noting worse than re doing instructions, or not being able to understand because you are in a hurry. I have a upscale kinda a house, man it looks great, I got this because we now have the grand kids a few days of the week, this along with the fence, they and the dong are in LOCK DOWN! and it looks like (the housewife show) YEA hit the remote...open gate, I feel rich! no stress , take your time , it feels so good when it comes together- ps I did have one q about a push button I added, she answered the phone, I told her my issue she said< 'honey it will not work if you are using a lighted door bell" I thought that was funny,in a good way... but correct. Got one no light, bada bing bada boom , taking out the trash? push the button!

Stephanie: I've had these installed for about 1 year. They've been trouble free. Hardest part of install was digging to bury the cables but that was expected. 1 issue I had was that the kit is designed for gates up to 18 feet. Being this is a dual gate system, simple math would suggest that a cable length of at least 36 feet plus a few feet at each end to reach the motor and control box. (At least 40 feet) The kit came with a cable roughly 25 feet long. :-| Fortunately I was equipped to extend the cable but added an hour to the job and additional cost. Should not have had to do this! I just recently ordered another system for a friend so we'll see how #2 goes for parts! Without saying, I would buy this product again. I cannot comment on tech support or warranty as I have not yet had to call for either. Hopefully the next one comes with all the required parts to do the job without additional cost and time required.

Pragmatic: Reviews of the GTO and Mighty Mule (MM) Do-It-Yourself (DITY) gates kits are mixed and many folks sustaining lightning strikes are unhappy with GTO/MM warranty coverage of their failed main boards or controller arm circuit boards. Other have has issues with the long term durability of swing gate operator mechanisms. We have had a GTO SL3000 12-volt DC solar slide gate operator in service for ~12 years with few problems other than an out-of-warranty failed main controller board at the 5 year point.

Our most recent acquisition and installation was a solar powered Mighty Mule FM502 Heavy Duty Dual Swing gate system purchased via from Amazon. Between the two we prefer the sliding gate design and operator function to that of the relatively slow swing gates operation for both security and strength, but both suffice to control access to your property which is the main point of automatic gates. The installation of the FM502 is straight forward the the operators have worked well in light use. The GTO SL3000 unit s a much heavier duty unit but is for slide (rolling) gates.

Some folks have complained the MM FM series swing openers are noisy in operation and we can only assume...

Farmer Doug: This is my second set of openers from GTO. The first ones lasted nearly 9 years without any problem but then just quit one day and would not open. After an hour of diagnostic testing while on the phone with GTO in Florida it was determined that the circuit board was no longer working correctly. I decided to buy a new set from Amazon.ca which were identical to my first set other than the name had changed to Mighty Mule. I felt that this way I would have some spare parts if ever needed. I installed the new set with all the same brackets etc. and everything is working well. No more opening gates in bad weather.
I am going to send my old circuit board to GTO in Fla. to have it analyzed and repaired so my old set will work again and I may install it on another gate.
The delivery was faster than expected and everything went smoothly. I hope I get another 9 years out of these openers.

Stanward S. M. Oshiro: The FM500/502 series opener supposed to be more heavy-duty than the other Mighty Mule openers. That's the reason why I purchased this one instead of the other opener units from the local home improvement store. The only thing better would be if it had an option of an extended warranty.

This unit comes complete with all of the hardware needed to do a proper installation. You should read the instructions fully, as well as watch the install videos on the included DVD.

***March 29, 2016 Update***
The unit is starting to fail more often. What is happening is, the Electronic Gate Lock does not unlock before the gate opens, thus causing the gate to stall.

Here is the catch, when using the keypad or the pushbutton (in the house, which both of these are hard wired), the gate always opens properly. It's something to do with the control board and the RF remotes that causes the control board to not unlock the electronic gate lock prior to opening. But it doesn't happen all the time, maybe once every 5 times. I am clearly out of the warranty period. I will contact GTO and see if a control board replacement is worth purchasing, or just buying a whole new...

Elkhound1971: Have been using these openers for several years on our gates and overall they have worked fairly well. Unfortunately, winds of over 120kms damaged one of the openers (certainly not the fault of the opener) and when I tried to get a replacement through the manufacturer (based in Florida) I ran into all kinds of problems. They have no warranty/service centers in Canada and they have no serious interest in providing any kind of service to Canadian customers. The cost they quoted me over the phone for a replacement arm (including expected shipping costs) was nearly as much as what this complete package cost! In addition, they wouldn't even give me a shipment date, other than to say they found doing export shipments to be waste of time and they would try to get around to the order once they had some spare time.

Please note - the service and delivery of this replacement package from Amazon was excellent. It was promptly shipped and I received the item well within the expected delivery timeframe.

One thing to be aware of in using these openers is that the manufacturer is still very much behind the times in not supporting HomeLink and they do not seem interested in updating...

R.Casa: I bought the model 502 some 12 months ago. I never managed to make it work. It may work a day or two but then start the problems: the beeper does not stop to beep; at any time, day and night (the neighbors love it!); means: the device is out of control and will neither open nor close; just beep. The whole is a complete misconception; the electronic part is fully out of control and will constantly signal whatever problem and/or simply not work. Sure is: you will open your door manually 4 out of 5 days! The charger that comes delivered is actually a transformer without any function. I also bought the 5 W solar panel: forget about; it will charge the battery on an extremely sunny day up to one cycle; from then on, you open your gate by hand (I live near the equator) for the next 24 hours. If you like to sit in your car and to realize that you have to leave it in order to open your gate: Buy the FM502; it'll keep you fit!
A complete waste of money and time for a perfect dissatisfyer.
