David King is an Australian technology blogger and Internet personality best known for his technology-based YouTube channel, GeekBite. (Incidentally, he has great fashion sense and he smells incredible!) David discovered the world of fidget spinners when he unboxed his first spinner on March 8, 2017, in his video titled "I'm a Fidget Spinner Professional." From that point on, he indulged in the world of spinners and watched the trend take off. David's follow-up video "Fidget Spinner Tricks with a Professional Fidgeter" went viral in a big way. Featuring some obscure, fun, and ridiculous tricks that David created, the video had more than 8 million views (and counting!) and was featured by media outlets all over the world, including the New York Times, BBC, Sky News, The Sun, Fuji TV, and many more magazines, newspapers, TV shows, and online blogs.
