Pre-Tightened Hinges for Stable Support: Hinges are designed with higher resistance to maintain stability during use. Initial adjustment may require firm pressure, helping the stand hold position securely under load. Compatible with 25.4cm to 43.2cm Laptops with Usage Consideration: Supports a wide range of laptop sizes. Stability may vary depending on laptop size, thickness, and weight distribution, especially for larger models. Performance Depends on Positioning and Weight Distribution: Best performance is achieved when the laptop is centered and properly balanced. Extreme angles or uneven placement may affect stability. Proper Setup on Flat Surfaces Recommended: Place the stand on a stable, flat surface and ensure all joints are fully opened and aligned before use for optimal performance. Durable Aluminum with Cooling Design: Lightweight aluminum construction with ventilation openings promotes airflow. Non-slip pads help keep the laptop securely in place during use.
