Do you think perceived value of a product from an advertisement give the user more or equal real value of the product, in terms of experience? why?

not all the time, determining the value over price is a long process, it varies from time to time.

Yes and no.

Some do portray an authentic image of a product that still needs to be tested. Others don’t, even if they tried to. A third type of advertisements isn’t even aimed at conveying value during the short time or space allowed (whether30 seconds on TV or an A1 folder or stand), but rather at capturing the attention of the customer using suspense, humor, originality, emotion or attraction and reserving some space in his/her memory for the next time he sees a certain product on a shelf or a sudden need pops up in his mind!

Examples:

1. Advertisements of slimming products, portraying before and after pictures of people who were fat and then became thin, are simply ridiculous to ME.
2. An advertisement of a nice new car model, indicating the enormous horse power of it engine in text and showing how it takes a "sporty" curve on a street is nearer to displaying a clear value.
