Okay, so I took a gamble on this portable hotspot after seeing mixed reviews. Here's my honest take after using it for a week during my Southeast Asia trip.
First off - the GOOD: This little guy is seriously compact and lightweight. Fits perfectly in my pocket alongside my phone. The battery life? Solid! Got about 8 hours of continuous use which was perfect for work sessions at cafes.
The BAD: Setting this up was... an adventure. The manual font is microscopic (seriously, who approved this?). Took me forever to realize I needed to insert the SIM card upside down (face up). Default login is admin/admin though - would've been nice if that was clearer.
The UGLY: Had major connectivity issues in rural areas despite claims of wide coverage. Worked fine in cities but dropped constantly on train rides between towns.
Final verdict? It's decent if you're tech-savvy and staying urban. Would I buy again? Maybe... but only if it was half the price.
