The LED strip is fantastic, it does everything it promises and more, it's worth buying. Through the app, you can set millions of colors either along the entire length of the LED strip or intermittently, meaning from 10 to 50 centimeters in different colors. It has hundreds of preset modes and you can also create your own (DIY). It also syncs with music, changing colors accordingly. As for durability over time, only the future will tell; I've had it for about two months and haven't had any problems. The LED strip can be cut every 10 centimeters and you can extend it up to 10 meters (Example: You need a 7 meter and 30 centimeter LED strip. If you haven't bought the 10 meter LED strip to cut it to your desired length, you can connect two 5 meter LED strips, which work with one of the two power supplies/controllers provided in the package, the others are left over. You set up your 8 meter LED strip, turn it on and all 8 meters light up, then reduce it by 10 centimeters at a time until you reach 7 meters and 30 centimeters. Then you mark the spot, unplug it, and cut it.) It's amazing but requires a bit of tinkering.

I could write much more but I focused on some information and some doubts that you won't find in the manual.
