Rigidity for the category of comodules over a HopdHopf algebra

On this page

https://ncatlab.org/nlab/show/rigid+monoidal+category

there is a discussion of rigidity (left-right duality) for the catagory of modules over a Hopf algebra. What happens if we look at the category of comodules over a Hopf algebra? Do we still get a rigid category? If so, does there there exist any general relationship between the left and right duals?
