1.Anti-slip silicon is used to enhance friction, and high-frequency typing is more stable and non-shaking. 2.Multi-point silicon anti-skid design increases friction and prevents notebook from sliding 3.Lightweight, portable, easy to store, stable and non-shaking, bottom lockable heat dissipation design. 4.Ventilation and heat dissipation design] Aluminum alloy material is easy to absorb heat and dissipate heat. The front tilt angle and open design provide more ventilation and airflow to keep the computer cool during use and can be easily removed. 5.[Lightweight and portable] - Extremely lightweight, so it can quickly retract into thin shape like a folding fan. Easy to carry, such as a bag with a handle. It only takes one second to open, close and install. Save a lot of time and space.
