SideTrak was a total game changer for me. I'm used to working on dual 27 inch monitors at my office for medical billing, coding and credentialing. Occasionally I take my work home where I only have a 15 inch laptop. By purchasing SideTrak, I am now able to efficiently do my work and even homework. It makes things easier having dual screens and SideTrak makes that possible. I purchased this during a black friday sale so I've had it for awhile and have had no issues. The cord is a solid braided cord so I dont even worry about it fraying or anything. Best purchase I've made relating to productivity.
