Let me start by saying this little gadget promised to be a game-changer for my frequent business trips. The idea of having a portable 4G router that supports up to 10 devices sounded perfect for team travels.

The good first: The compact size is fantastic - it easily fits in any pocket or bag. I loved the LED display showing signal strength and battery life. The 2100mAh battery indeed lasted me through long train rides (though not quite the claimed 72 hours with actual usage). When it worked, speeds were decent enough for emails and light browsing.

Now the frustrations: Like some reviewers mentioned, finding the SIM slot was confusing at first - it's cleverly hidden under a panel that doesn't obviously look removable. The instructions (what little there were) didn't help much either. I had to watch an unofficial YouTube tutorial to figure it out!

The biggest issue? Inconsistent performance. Some days it worked like a charm, other times it would randomly drop connections even with strong signal. Support was non-existent when I reached out with questions.

Would I recommend it? Only if you're tech-savvy enough to troubleshoot on your own and don't need rock-solid reliability. For occasional personal use, it's okay, but business travelers might want something more dependable despite the higher price tag.
