What are some examples of false promises made in marketing

Some false promises made in marketing would be:
• The need for the good(s) or service(s)
• The quality of the good(s) or service(s)
• Not mentioning any other fees that may be included, these fees are known as 'hidden fees'.

In marketing,a lot of empty promises are made. Meaning that the seller will claim a product "will change your life" when in reality they cannot guarantee that.
