Advance 2.0 relieves and prevents repetitive strain injuries and other problems that can occur when you use a conventional mouse. Because Mousetrapper is positioned centrally in front of the keyboard it encourages an ergonomically healthy position that keeps your arms close to your body and your hands near the keyboard. This helps you avoid and in many cases relieve strain injuries that can arise from over-stretching your arm, as you do with a conventional mouse. It eliminates the need to stretch beyond the keyboard while using the mouse. The wide, cushioned wrist supports also relieve strain on your neck, shoulders, arms and wrists.
