Vertimas - Prancūzų-Ispanų - Évitez nos imitations

Lily, where is "of our products"?

I don't think it's needed, since it is implied that the warning is about our products. That's a commom phrase to warn costumers about the existence of imitations and who usually states that is the manufacturer of the original product. That's like: "Beware of the dog". We don't have to inform whether the dog is a pit bull terrier or a doberman, but it's implied that it must be dangerous.
