Okay, so I took this little black rectangle on a 3-week Eurotrip and here's the tea ☕️

The Good Stuff:
• NO SIM CARD DRAMA! Landed in Paris and had internet before I found my luggage 🧳➡️📱
• Battery lasted through 14hr travel days (airport ➡️ museum ➡️ bars) with ~20% left
• Connected my phone, tablet AND my friend's devices simultaneously without lagging
• That "intelligent network selection" actually works - hopped between carriers smoothly in Switzerland's mountains

The Annoying Bits:
• The app interface looks like it was designed in 2010 (why so many confusing menus?!)
• Had one random disconnect in Berlin - fixed by restarting but still 🤷‍♀️
• Comes with this weird plastic film "screen protector" that peeled off immediately

Pro Tip:
The included global data disappears FAST. Top up via app before trips - way cheaper than airport SIMs!

Final Verdict:
4/5 stars ⭐⭐⭐⭐
Would I buy again? Absolutely - worth it just to avoid foreign SIM card kiosks 👑
