Compatible Devices: PS Portal, Rog Ally/X, Stream Deck/Oled, Legion GO, Switch/Switch EL, smartphones, and various other devices. [Metal Material - High Stability & High Durability] The internal core structure utilizes high-precision metal alloy materials, forged through multiple processes and reinforced for extremely high mechanical strength and impact resistance. Even with accidental drops or strong external impacts, deformation or damage is unlikely, demonstrating outstanding physical durability. The surface is coated with a multi-layer anti-rust and anti-corrosion coating, effectively preventing oxidation and wear from daily use. This extends the product's lifespan and supports long-term stable use in various environments. [Hollow Ventilation Design - High-Efficiency Heat Dissipation & Structural Stability] The overall structure adopts a scientific hollow layout, forming a stable triangular support system after installation. This significantly improves the overall balance and torsional resistance performance, making device installation more stable and secure. A large ventilation space is secured in the center to promote airflow and accelerate heat dissipation. This prevents overheating of the device during long operating hours, without compromising its original heat dissipation performance, achieving both safety and convenience. [Silicone Ring Scratch Prevention Protection - Comprehensive Protection of Contact Surfaces] High-elastic, flexible silicone rings are attached to the important contact surfaces of the product, and the base is fully covered with thick silicone non-slip pads. This effectively improves friction and cushioning performance, completely preventing damage to the device's appearance from scratches, vibrations, and slippage. It provides gentle and comprehensive protection during installation, movement, and daily use, completely eliminating the buyer's concerns about wear and tear. [Compatible with All Models]: Designed to be compatible with all models, the upper and lower charging ports are applicable, convenient for long-term use.
