A Logitech controller, which was reportedly used as a steering wheel for the OceanGate Expeditions submersible, that went missing en route to the Titanic wreckage in the Atlantic Ocean on Sunday, has sold out after much hype around it.

The submersible, known as Titan, was carrying a five-people crew, including Hamish Harding, a British billionaire and adventure enthusiast, and OceanGate’s founder and CEO, Stockton Rush when it went missing, equipped with just four days of oxygen supply. It lost contact with the Polar Prince research ship, roughly 1 hour and 45 minutes after it began descending underwater.

As experts began going into details about the kind of technology that the submersible was using, it was found that the vessel was being controlled by a Logitech F710 wireless PC game controller from 2010, which shocked a lot of people on social media, especially because the passengers reportedly paid $250,000 to take the perilous ride that ultimately turned deadly.

Although most social media users have put the cost of the controller at $40, according to Ars Technica, the device retails on Amazon for about $29.99. It is a wireless dual-thumbstick gamepad for PCs that use 2.4 GHz communications to a USB receiver.

Despite its chunky design being outdated, it has been in continuous production for 13 years. The Cheap Ass Gamer Twitter account posted an Amazon link to the Logitech F710 controller on Twitter after news that the submersible also used the same technology spread online. As a result of the hype surrounding the device, the item quickly sold out.

The exact cause of the submersible’s disappearance remains unknown as marine officials from multiple countries have joined in a massive-scale search and rescue mission, racing against time. On Monday afternoon, the US Coast Guard estimated that the Titan may have about 70 to 96 hours of oxygen left.
