Despite supply issues, Sony’s PlayStation VR headset has sold approximately 745,000 units since its launch in October – well ahead of its high-end competitors, the HTC Vive and Oculus Rift.

That’s according to market research firm SuperData, whose most recent insights report has the HTC Vive as selling 420,000 units in 2016, and the Oculus Rift at 355,000.

The real winner in the field however was Samsung, with its lower end Gear VR mobile headset shipping close to 2.3 million units this year.

SuperData previously estimated that the PSVR would shift 2.6 million units in 2016, but downgraded its forecast last month, citing a “modest marketing effort” from Sony.
