If it is original, it can only be said that this product is produced by the original factory. If it is original, it is a complete set, so it is better to compare it with the original factory, but after all, there is only one, so if it is changed, it can only be changed to the original factory. To put it bluntly, when the original product breaks a part, the original part is the best substitute product.

The difference between the original factory and the original factory is quite big, but people don't think so in life, because we only care about the original factory and the original factory when buying big brands, and generally don't pay attention.
