With the company shut down, it looks like someone from the Essential team or at least someone associated with the former smartphone maker tried to sell off some hardware, including an unreleased product. But the product has since been pulled. The offer included an Essential Phone in Ocean Depths colour, the clip-on 360-degree camera, a case for the camera, headphone adapter, earbuds, and the unreleased dock. The auction was up to US$535 (around CA$709) with 39 bids before it was pulled.
