After testing this 4G LTE USB modem hotspot for a week, I have mixed feelings. The compact design and ability to connect 10 devices simultaneously is impressive for travel. I used it during a coffee shop work session with my laptop, tablet, and phone connected - the speed held up well for basic browsing.

The 300Mbps advertised speed feels accurate when you have strong signal (I got about 275Mbps in downtown areas). The battery lasts about 6 hours with moderate use - decent but not exceptional. Charging via USB-C is convenient though.

MAJOR WARNING: Like many reviewers experienced, this device failed to work with my US carrier SIM (T-Mobile). After hours of troubleshooting APN settings, it still wouldn't connect. The 'unlocked' claim seems misleading unless you're in specific Asian/European markets.

The build quality feels cheap - the SIM card tray broke on my third use. For $60, I expected better durability. It does get quite warm during prolonged use too.

Final verdict? If you're traveling internationally (outside North America) and need multi-device connectivity, it's an okay budget option. But US buyers should steer clear - most negative reviews come from frustrated American customers facing compatibility issues.
