I'd say you should go for a vet rather than midias. No offence meant to midias, but the review serves two purposes and one of those purposes is receiving feedback and telling everyone about the quality of the product, the second is publicity. And if you want publicity, go for someone famous.
Exactly, If you were buying it the review would be positive no matter what. The review is based completely on product quality and service. You may be giving some one a free laser to look at and review, to have them potentially say bad things about your product.
