When users connect to their local area network (LAN), lightning and power surges cause disconnection from the Internet and damage to motherboard LAN chips. Eventually, the LAN chip will cease to function causing great inconvenience possibly entailing a difficult and costly recovery process. The Lightning Guardian Angel, GIGABYTE's patent-pending LAN surge protector, is the best solution on the market to protect your system. The Lightning Guardian Angel has been precisely engineered to provide innovative circuit protection. It will protect all equipment with an RJ45 connection from surges coming through the LAN. The Lightning Guardian Angel will help users maintain a stable LAN connection and prevent future LAN chip damage caused by any external factor (e.g. lightning, power grid, microwave, elevator and other high-power electrical devices, etc.).
