The GL.iNet GL-XE300 (Puli) is a compact yet powerful industrial IoT gateway that combines versatility, security, and ease of use. With its ability to convert 4G LTE signals into Wi-Fi, this device ensures uninterrupted internet connectivity, making it ideal for remote locations or areas with unreliable wired infrastructure.

One of the standout features is its OpenWrt pre-installed system, which allows for extensive customization and DIY projects. The inclusion of OpenVPN, WireGuard, and WPA3 ensures top-notch security, while the dual Ethernet ports and USB 2.0 port provide flexibility for various setups.

Users have praised its ease of setup and advanced features like the VPN Killswitch and multiple internet source options (4G-LTE/LAN/Wi-Fi repeater). However, some noted limitations include the lack of USSD code support and the absence of a physical IMEI on the device's exterior.

The built-in 5000mAh battery is a game-changer for mobile applications, offering long-lasting power. While the device supports only 2.4GHz Wi-Fi, which may lead to interference in crowded networks, its performance remains reliable for most tasks.

Overall, the GL-XE300 is a robust and secure networking solution worth every penny for those seeking flexibility and reliability in their IoT setups.
