Question: Does it fit the Raspberry pi 4b?
Answer: The specified display est compatible with microcontrollers such as Arduino. To connect it to the Raspberry Pi 4B, it is recommended to use an I2C converter, which will simplify communication and reduce the number of required connections. Alternatively, it is possible to directly connect the display to the Raspberry Pis GPIO pins, but this requires appropriate wiring and code modification to support a parallel interface.

Electronic components themselves cannot be rated. They arrived fine, on time, from a business standpoint everything is okay. Otherwise, we haven't used them in any way yet. They are lying in storage.
