Question: Is there a installation video or a installation manuel available?
Document: If I were to make any recommendation, I would recommend going with the 400mm arm kit just because the extra length arms make it easier to set up the mounting location. While the 300mm arms in this kit do the job, I did have to pay attention to measurements on the pivot mounts on the gate posts in order for the gates to fully open and close. The 400mm arms are more forgiving with mounting locations since there is more arm travel available to work with.
This system is about half the cost of the cheap Mighty Mule and other retail homeowner kits. I contacted the seller who sent me on-line manuals to review. After ordering, the kit arrived in 5 days. Nice! Everything was there and after inspecting, I have to say that I am amazed at the quality of all the components. Nothing is cheap or anything but the highest of quality.
The product is of excellent quality. The manual is in readable English. It has an auto program, so that if the program goes bad (I left a padlock on and tried to open it) the gate reprograms itself. I asked a couple of guys to help me set it up. Unfortunately my posts shape was not quite convenient, so I had to build some customs brackets. I recommend the 400mm instead of 300mm if it is your first experience or not sure about the posts and hinges.
That takes a little longer to close. Open works the same with battery or AC power.I e-mailed Jason, the distributor and vendor, several times with questions I had and he was very knowledgeable, articulate and quick with replies.
Once at the job site, it didn't take long to set up and get this system into operation. I didn't have AC power at the site, so I used an extension cord to compare the function of the solar/battery verses the AC transformer options. Satisfied that the solar/battery operation would work fine for my needs, I was able to save myself the time and trouble to put in AC power or run low voltage wire back to the house for the transformer to be remote powered from the garage.
It comes with three remotes, they don't look very strong. I am ordering a couple more.
If you are using round gate posts, this 300mm kit is more than enough to make the install easy.
I've been searching for a dual gate control system for some time now and it seems there are two basic types; cheap junk and over priced commercial grade. I just couldn't justify the commercial grade costs and was just about to waste some money on a Mighty Mule system, which I've come to learn lasts about 2 years before they break down.Then I stumbled upon the E8 brand. At first, I was sure this was some sort of scam.
Answer: no
