I purchased the Spitz Plus (GL-X2000) myself and have now used it across 13 EU countries – and even beyond. Inside, it holds two SIM cards: one physical SIM and a clever eSIM adapter from 9ESIM loaded from me with multiple profiles. Beyond the standard features, I’ve installed Syncthing, which I documented in detail on my website. It allows me to sync data from home directly to a tiny USB stick on the router – no phone or laptop needed, even while on the road. It’s like having a personal cloud that travels with me.
New: On this trip i also added a little x86 server to the car with Proxmox, Homeassistant, NAS, Emby-Media-Center. Also documented at my website.
Most of the time, the Spitz Plus quietly does its job tucked away in a closed kitchen cabinet – or, when the door’s open, it hides behind boxes of teabags and other breakfast supplies. 
What I really appreciate is the powerful, well-cooled SoC that offers plenty of performance headroom. I’ve connected the cellular antenna ports and one of the WiFi ports to an external roof antenna, which gives me noticeably stronger signals than my phone, especially in remote areas. WireGuard and Tailscale work flawlessly, and the current firmware makes eSIM setup surprisingly smooth and user-friendly.
The GL-X2000 is designed with 12V and 24V input environments in mind, such as Recreational Vehicles, offering a wide voltage input range of 9~36V and a 5.5×2.1mm DC adapter to ensure device compatibility and stability.
My only real complaint is that the OpenWRT base is still from 2019. I’d love to build and customize my own firmware again with full compatibility.
Of course, it would be nice to have 5G support and dual SIM standby, but those features are available on the higher-end X3000 model.
Final Verdict
Based on price and performance, I’d absolutely buy the Spitz Plus again. It’s a reliable, flexible travel companion – and one of the best mobile routers I’ve ever owned.
