SideTrak Swivel

The SideTrak Swivel is a unique 12.5-inch FHD portable monitor designed to attach directly to the side of most laptops via a patented swivel mount, saving desk space. It connects via USB-C and can rotate 360 degrees. Targeted at users with extremely limited workspace, like on airplanes or small coffee shop tables, its design innovation is its key selling point. It scores well for solving a specific spatial problem and has gained a dedicated user base.

Customer support is noted as responsive. It's a paid, niche product that offers great value for its unique form factor and mounting system.
