2-minute Review [Negatives]
  • Because of the glass-based panels, the surface is prone to finger prints and smudges
  • The concentric circle design may be too shiny for some
  • Asus' ZenUI is pretty bloated, with a lot of unnecessary apps, leading to a cluttered experience
  • Although day to day performance is good, there are visible lags on heavy games like Asphalt 8
