I really like the aesthetic, both of the product and your website. One point of feedback, since you ask: the website makes it really hard to get a sense of the material. You describe it uses recycled machined aluminium for the body and some polymer, but it's really hard to get a sense of the actual hardware from the CGI renders. One thing that especially jumped out at me was that in the videos, such as this one: https://electronicmaterialsoffice.com/video/Turntable_mobile... there appears to be some kind of film grain overlaid on the video. This makes it really difficult to assess the texture of the material.

Oh and I really like the idea of having a physical switch for multiple Bluetooth paired devices.
