The keyboard has undergone two prototype iterations and utilizes a traditional top-mount assembly for reliable performance, appealing to both new and experienced users. 

Key specifications include an 8.0° typing angle, a front height of 19mm, and compatibility with both solder and hot-swap PCBs. The construction features anodized aluminum for the top and bottom cases, along with a sandblasted-finished copper front badge and internal weight. The expected price range is between $350 and $450, depending on color options. Additional high-resolution images are available for better detail viewing.
