    Gotta tell you, a name like "Radioddity" right away suggests english was not the marketing director's mother tongue. Reminds me of the story about GM when they introduced the Chevy Nova to sell in Brazil.

    Sales were just agonizingly slow, compared to how the same model sold in other countries.

    And then someone explained that "No Va" in portuguese means "No Go".

    Can't remember what they changed the name to.
