Refund/reshipping

Have any of you had experience using reships in order to refund US stores?
I found this site: https://www.shippn.com/ , which uses individuals for reship services.

Has anyone here had experience using such a site for refund/reships?

I used shippn quite a few times -

The pros that the address that you get is unique for refunds because almost all reship is saturated or blacklisted.

The downside is that shipping fee is very very expensive.
