🏠 Home/Remote Worker Reviews

⭐⭐⭐⭐⭐ Priya Nair - Remote Software Developer, Rural Area
"Living in a remote area with no DSL or cable, this router has been a game-changer. Installed in November 2024, it’s now my primary internet source via a local LTE provider. The metallic casing helps with heat dissipation, and I’ve had zero crashes—even during summer heat. OpenWRT lets me run ad-blocking and QoS scripts, which keeps Zoom calls crystal clear."

🛠️ Industrial Site Deployment Reviews

⭐⭐⭐⭐☆ Carlos Mendez - Field Operations Manager, Construction Firm
"Deployed three units across temporary job sites starting June 2025. The rugged build and 4G failover keep our project management tablets and security cams online. We connect legacy surveying tools via the four LAN ports. Only downside: USB 2.0 is a bit slow when backing up drone footage, but otherwise, extremely reliable in dusty, high-vibration environments."
