Carousel on the e-commerce website, it is really needed? [duplicate]

This question already has an answer here:

Would you use a carousel to show all products listed by specific categories into the header?

Consider that there are already other 3 navigation menu on the same page to access them on the top and right and another on an ad-hoc map to the centre of the page.

  • The carousel has no common controls like arrows but only a line below that the users must drag and drop to scroll all the product.
