A definite NO! Even if your product is a leader in its category, an open a marketing claim with this statement may even damage it.
A new study by Kellogg School of Management showed that if a product is called the best, its chance of success is reduced. The reason is that maximum expectations are created in minds of customers, who then expect to be amazed. Anything that is not absolutely perfect seems unsatisfactory. During the study, the surveyed consumers felt sorrow or dissatisfaction if the product did not meet their expectations.
Adjective "the best" is therefore a hidden danger, whom marketers must be aware of. The solution is to use other superlatives, which set customers' minds differently and thereby reduce the dissatisfaction with the product.
