Rony Abovitz, CEO of the secretive virtual reality startup Magic Leap, took to Twitter on Thursday to defend claims that his company is overhyping its flagship product, a powerful VR headset indistinguishable from everyday sunglasses. In a series of often-humorous tweets, Abovitz hinted that his company had experienced issues with early prototypes, but refuted a report from The Information this week that claimed Magic Leap may have “oversold” what its headset can do.
