The treadmill Jennifer had bought, Invigorate Me, had only been on the market a couple of months and already had hundreds of stellar reviews with exaggerated statements like “life-changing”, “the best I’ve ever had”, and “a wild ride of intense physical enjoyment.” Who enjoyed working out? Jennifer had been won over by the more modest endorsements, like “very thorough and constantly adjusts to your needs” and “I’m definitely happier, more fulfilled, and more invigorated.” Little did she know the reviews weren’t for the treadmill but the cyborg personal trainer that came with it.
