360-degree rotatable base makes it easy to share your laptop screen with others during collaboration. Heavy, stable construction. Made of high-quality metal, the base is heavier than normal laptop risers made of lightweight aluminum alloy. Upgraded joint screws securely lock the laptop at the desired height and angle, delivering less wobble and steady support. Enhanced ventilation. The hollow design creates more space for heat to escape, helping prevent notebook overheating. Adjustable height and foldable design. Multiple angles and adjustable height enable ergonomic use, with eye-level screen positioning to reduce neck strain. It folds flat for easy storage and a tidy desk. Use scenarios: - Team meetings or project reviews: share your screen quickly and collaboratively without repositioning your setup. - Coding, design, or data work in a shared space: stable, secure support that minimizes movement while you work. - Remote presentations or video calls: keep your laptop at an ergonomic height while maintaining a clean, compact workspace.
