In one sentence, it is the ideal choice for converting a mobile phone or tablet into a portable gaming console/emulator (especially considering its price).

On the positive side, its plastic is of good quality, the response of the analog sticks is more than satisfactory, and mainly their position (due to the design of the grips which are outward, like any regular gamepad), as well as all the buttons and the D-pad are ideal since they are located just below the "arc" where the thumbs can move while holding the controller or the fingers for LB, LT, RB, RT. Also, the A, B, X, Y buttons as well as LB, LT, RB, RT are almost silent. The Select, Home, and Start buttons are located on the left side below the D-pad while on the right below the A, B, X, Y, there are two +/- buttons for adjusting the volume and three (previous, play/pause, next) for music applications. These are not silent but they won't be used often during gameplay. Although it’s not something special, I found them convenient for lowering or raising the sound without having to let go of the grips of the controller or even to stop a song that I had playing alongside the game.

On the negative side (just to mention something), the triggers are not analog, although I never intended to need them (serious simulators like racing games I won’t play on mobile...)

Important: Although I encountered no issues pairing with the Bluetooth of the mobile phone and tablet, I had to read the instructions to choose the correct type of connection. That is, simply pressing home connects it but does not respond correctly (it recognizes it as a mouse). To make the connection and respond correctly as an Android controller, the X must be pressed while pressing home and then pairing must be done. After that, no application was needed for button mapping. Everything needed was done through the emulator settings.

I don’t know if similarly more expensive controllers offer anything more, but at least for my needs, I see no reason to spend more money.

It is a mouse in the shape of a remote control, yes

It's pretty good for its money. Obviously, it's not for competitive gaming and as convenient as a PS4/5 controller, but it does the job very well. Personally, I have it on my tablet to play PS4/PS5 and PC-Steam streaming and it's great for single player games. *** WARNING: IF YOU WANT IT FOR PS REMOTE IT IS NOT COMPATIBLE. THE APPLICATION ONLY WORKS WITH THE GENUINE CONTROLLER AND THIS PARTICULAR ONE CAN ONLY WORK WITH THE PSPlay APP, WHICH COSTS 7.49 EUROS AND WORKS PERFECTLY. ***

For first use, it seems good, after a lot of searching, I ended up with these because they have many positives.

1st They have buttons on both sides "see prices" (which seem durable, time will tell).
2nd The application it has, Shooting Plus V3, is incredible because you can play any game you want by placing the buttons wherever you want and saving them, otherwise it has game buttons for all the popular ones already!
3rd It works for both tablets and mobile phones (it is long, it even works for something longer than a tablet, imagine that!)
4th Besides being for mobile/tablet, it also works without it by connecting to a Bluetooth smart TV or a console and you can play as a regular controller.
Now time will tell how long it will last, but for its price, it is definitely worth it and more.
All of this is happening on a Poco F3 Android!

Do not buy it for iPhone. It works only until iOS 13. As soon as you try to use it on an iPhone from 6s and onwards, which have updated to iOS 15, it doesn't work. It displays a message to report it to Apple to fix it.
Luckily, I also have Android devices, so maybe the money won't go completely to waste
