NARB recently announced a decision in a case involving various claims that Shark Ninja made in an infomercial for its Shark Stratos Powered Lift-Away vacuum cleaner, including claims about how well the vacuum picks up hair and how well it reduces odors. The decision covers a lot of ground – Dyson challenged six express claims and nine implied claims – but we’re just going to focus on a few issues that come up regularly in our conversations with clients about claim substantiation.
