The Mousetrap is a marvel of adjust-ability and ease of use. The basic unit is thick, so it fits nicely under most laptops, and does not protrude into the operator area. Precision machined from solid aluminum, the unit remains solid and does not rattle or shake when driving down the harshest of roads. When needed the unit can be extended and swiveled left or right. Safety aspects built in include a latching system that will not allow the unit to extend in the event of an accident, yet will allow the unit to automatically retract so that it minimizes the chance of injury. Another great safety feature is the swivel limit adjustment that allows the end user to select their desired amount of swing. This is great for limiting how far users can position their laptops into an air bag zone, or too close to the steering wheel and other operator controls.
