I have a particular product in mind, but more generally if a company sells a product that people are given to expect will perform a certain function (eliminate mosquitoes, for example), is there any action that can be taken when the product is, by design, incapable of performing the expected function (i.e. "Mosquito Eradicator 9000" is just water).
Companies tend to be very careful to make sufficiently vague claims that are TECHNICALLY true, but also induce consumers to expect something that is not true. But surely, there's a feature of modern legal systems that can cut through this kind of double-speak, right? I'm in the US, but I'm thinking this is probably similarly true elsewhere.
