I think the issue with "export reviews" is that it's not a major consumer advertising term. There's no great business advantage to a particular export company owning this domain, it is not a high traffic term. The companies build up their business through reputation and service, they can't use high traffic internet terms because they don't exist.
The other problem is that there are many, many export- alternative names a company could choose. You do not have "the" high traffic term, because there is no high traffic term to own.
That's why this domain will be hard to sell, but good luck anyway.
