After weeks of testing the Cudy LT12 4G LTE router in various scenarios, I'm thoroughly impressed by its performance as a primary internet solution for remote locations. The compact black unit with four external antennas looks like a mini enterprise-grade device, and it delivers on that promise.

The Good: The dual SIM capability saved me during an ISP outage - it automatically switched to my backup carrier without dropping my video call. Speeds consistently hit 80-120Mbps downloads in my suburban area, more than enough for 4K streaming on multiple devices. I particularly love the WireGuard VPN integration; setting up secure remote access to my home network took just minutes through the surprisingly intuitive web interface.

The Bad: The plastic casing does feel cheaper than expected for the price point - I'd recommend keeping it in a well-ventilated area as it gets warm during heavy use. Band locking requires some technical know-how that casual users might find intimidating (I had to Google instructions for my specific carrier).

Real-World Use: During a weekend cabin trip, I connected security cameras, two laptops, and our phones simultaneously. The signal remained stable even when positioned near a window facing away from the cell tower. The daily auto-reboot feature mentioned by another user genuinely helps maintain performance over extended periods.

Verizon Users Beware: Like several reviewers experienced, Verizon's compatibility issues are real. I successfully used mine with T-Mobile and AT&T SIMs without IMEI cloning hassles.

Final Verdict: For digital nomads, rural users, or as a business backup solution, the Cudy LT12 delivers exceptional LTE performance despite its plasticky build. Just confirm your carrier's band compatibility before purchasing.
