It does make it worse because by accepting a free item they have a commitment to making at the very least a decent review, they didnt have to accept it, they could have sent it back (specially considering it was their prototype, you cannot buy a product at that stage). If they bought it and decided to shove it up their ass to test how well it cools their intestines I would find it extremely weird but fuck it, they bought it and they can do w/e they want with it.
