It's wasted money, I've had it for less than two months and the touchpad doesn't work, ruining the entire gaming experience

As others have said, the battery when you turn on the PS sometimes appears full but after a while, it gives you a low battery notification; however, if it is indeed charged, its duration is long. In some games, it does not respond to certain commands like many knock-off controllers. For emergency use, it is good, but I wouldn't use it as a primary due to the issue with the commands (e.g., it won't run, but it will walk and will require a lot of effort to respond)

Whoever gets it should know that the battery doesn't last, and no matter how long you charge it, the battery doesn't fill up completely. You disconnect it, and it shows 2 bars on the battery, which deplete quickly. The one I got in black is completely simple; I won't buy it again

Why when I connect a second controller does the first one disconnect? How can they both work together simultaneously?

Good but it has two issues, one is that when you turn on your PS4 it shows that the battery is full and immediately after that it shows that it is empty, and sometimes it freezes. It is good.
