Very good. I managed to synchronize 4 different air conditioners. It found the frequencies for all of them. It would be good if it also had keyboard locks!

It has all the basic functions of an air conditioner except for the turbo mode. Additionally, whether you press the ON/OFF button to turn on the air conditioner or to turn it off, the screen of the remote control remains lit. I really don't know what the purpose of this is, just like the light on the top part. Apart from these, the time for setting it up depends on the brand. It took me 3-4 minutes to find and synchronize it.

It doesn't work for me, it connects and then disconnects again... Difficulty in connecting with the air conditioner, even though I have the device's code... Also, small size and unreadable screen, I was disappointed... I do not recommend it

I struggled a bit but managed to do it.
It has many codes and searches for them like the TV channels, you just have to press the button to go to the next code, it doesn't go automatically. However, it is possible, it is not impossible. And it works great. And because the price is low, I bought two to have a spare.
I highly recommend it.

For my Panasonic air conditioner, it works perfectly. Just be careful with the settings and matching the appropriate code with the air conditioner brand. Everything has been fine for 3 years.

I have bought 2 of these. The first one suddenly stopped working without any apparent reason after one year. And I must say that I didn't handle it roughly... Now I am using the second one - time will tell. It has a front LED flashlight but it doesn't have a backlit screen.

Perfect controller, within 5 minutes, found and locked the air conditioner, even though it is non-branded and not on the list. I bought it for 3 euros from a toy store.
I would give it five stars if the screen was a little bigger.. Oh, I also found it on the internet with various other names, but much more expensive.
