Unfortunately, its frequency is not the usual one that the majority of garage door remotes have, so they do not synchronize.

I, in order to copy from the main remote control, pressed and held A and D on this one, and on the other, for example, the A that I wanted to transfer

I bought 4 because of the low cost and because there are 3 of us who will use them. Out of the 4, one could not copy the codes, the rest are ok but to open the garage door you have to get very close to it.
Conclusion: I have to buy others, they are not worth even the 3 euros each, sturdy construction but...

Purchased for transition from another type of remote control, but unfortunately the other remote is of variable code and cloning is not possible.
However, the construction of the remote control is excellent and the battery replacement process is quite simple.

Stable value and reliable result, "communicates" with everything, a price above 5€ is not recommended, it is one of the most "basic" on the market, at the promoted price it is HONEST!

Everything is ok, including the programming by following the instructions and from the users. I don't understand why the red has a different color... The shape didn't suit me much, it's the same as car keys and that doesn't help in the dark.

I bought one to try and it was programmed easily according to the instructions. Then I bought 4 more but I couldn't program any of them, neither with the instructions nor with the video. Their LED is not blue like the original one (I don't know if that matters), but red and it blinks differently during programming, that is, when you press both remotes (old/new) at the same time to clone the code, it blinks twice and then stays off (not on as the video says and as the first one did). All 4 did exactly the same and none of them worked. I am returning them.

Super price €2.5. It copied just fine from an identical remote in the following way:
1) On the NEW remote (important so you don't erase the frequency from the old one and get locked out), press the 1st and 2nd buttons (from top to bottom, A+B) and the blue light flashes.
2) Next, do not release A and press B three times in a row. The blue light flashes again.
3) Bring the two remotes close together.
4) On the OLD remote (the one you want to copy from), hold down the button that opens the door.
5) At the same time, on the NEW remote, press the button where you want to copy the frequency. The blue light flashes rhythmically at first and then very quickly.
6) The frequency has been copied. Test with the NEW remote. If it doesn't work, try again (it took me 3x).

In the same way, you can copy the frequency to any button position you want on the new remote.

If the key is old, you need to transfer it to the new case (this one). There is a small pin that holds the blade, it was easier than I thought. You transfer all the old components to the new empty case

programming is not possible by the included instructions. they do not refer to the delivered remote controller. waste of time and money's

As with another model I bought, I tried to set it up with the instructions it comes with, nothing, I tried with some help from comments, nothing, finally the video that a friend posted on YT works!! I attach:

button A/1 https://www.youtube.com/watch?v=aBWZFyUlTro
buttons B,C,D/2,3,4 https://www.youtube.com/watch?v=3asofee3gyg

***ATTENTION DURING TRANSMISSION YOU MUST TOUCH THEM EXACTLY AS IN THE VIDEO BACK TO BACK!!!

***SOMEONE SAYS IT'S FOR EXACTLY 433MHZ, THAT'S NOT TRUE. AT LEAST IN THE ONE I GOT, I TRANSFERRED FROM A REMOTE THAT SAYS 433.92MHZ ON IT.

easy to copy and very good quality, my own controllers which I paid expensive for are completely rubbish in terms of quality.

It does its job with the help of someone who wrote here, otherwise not. The instructions that come with it are irrelevant.

It is quite good as long as it synchronizes with the transmitter

Probably for the trash. I managed to enter only one code, it wouldn't accept any other code at all. I put the same code on 3 buttons, but a second one not at all.

Good quality. Very easy frequency copying. I got it from Kallithea from Nettop.

If the remote control works only once and then stops, it is very likely that your old remote is a rolling code, so it cannot be copied and needs another remote and another process.

This one is fixed code and works perfectly — a real powerhouse in performance! With my old remote, I had trouble every time to make it work because it had a very low range, and I thought the motor's circuit board was to blame.

To copy buttons B, C, D in my case, it required the process one by one and not one after the other continuously. Why search for which button to press and why let one button break from use?

From the store in Elefsina, they were asking us for €20 for each remote control and that we had to take the board there. People are laughing.

Very good remote control for devices that do not have a Rolling code.

There is no user manual-programming in the package nor in Chinese! UNACCEPTABLE! How will the buyer program it without instructions? Another user on skroutz had posted a link on YouTube with programming instructions:
https://youtu.be/aBWZFyUlTro?si=JvZqTRNUH1skAJ_7

I bought it to copy 4 remote controls that I use. Following the above instructions from YouTube, only one of the four remote controls seemed to copy it according to the LED flashes. But ultimately, as it turned out when I went to use it, not even that one had been copied correctly and the garage door did not work.
Success: 0/4

If you think it will copy your remotes, good luck!

If I knew they were gonna send me remotes with the icons as seen in the picture instead of A B C D I wouldn’t have purchased them as I install sliding gates and these icons are not relevant to the operations of a sliding gate

It synced relatively easily, but you have to figure out where to press the button and for how long.

very good and beautiful control. good material and easy programming I set three codes in 5'. it worked perfectly. value for money I recommend it. be careful it is ONLY for fixed code 433gh

It copied the code from the old remote on the first try. In fact, I wrote the same code on all 4 buttons so I wouldn't have to search for them in the dark. Perfect

For its price (3€), very value for money. I have programmed codes from 4 garage doors. WARNING! It is only for a frequency of exactly 433Mhz! And of course only for fixed codes.
Programming is super easy.
The only downside is the difficult opening for battery replacement

very easy setup, works perfectly, for those it doesn't work for, it simply doesn't cooperate with the board because it is on a different frequency.

Very good remote control, with very good range compared to others! Thanks to the friend below who posted the link with the instruction video for cloning it! Very easy process when you have it ready as information!

Of the few that were programmed immediately. A similar one (but with a blue LED) never worked. This one has a red LED. I don't know if it's a different batch or another model, but they were purchased from different stores.

It works only at a frequency of 433MHz. This practically means that if the remote control you want to copy operates at a different frequency, then it does not work.

It seems high quality. The rubber buttons are pressed easily. It was programmed very easily. Buy it.

I went to the locksmith to have it set up with the original and he told me that he wouldn't take on the job and suggested his own for €20. So, it's a good idea to ask if someone can take on the task of syncing it with the original before the purchase.
