Review title: Mediocre at best
Product review: Failed to guess "particle accelerator," "atom," "bomb," "matches," and even "unicorn." What a waste. If you come up with your mundane, everyday articles of daily living, then it's possibly accurate about 60% of the time (at least by my estimates). But otherwise, avoid it. It fails to measure up.
