Essential!
Great little device that helped us stay connected throughout our vacation in Japan. I did notice that sometimes it would shut off even when charged, which was annoying while navigating since no WiFi means no data (even will full cellular service bars). Drop off was easy :)

Life Saver!
We got the Diamond package, with the piece of mind that we wouldn't run out of data. Our American mobile plan only gave us super slow 2G speeds that we couldn't do anything with. Thank goodness we had this hotspot! Google Maps was a necessity to get around, as well as Google Translate. The only thing I wish is that I would receive a confirmation that they received my returned equipment.

No complaints...only recommend
Second time renting..... not disappointed at the service provided. Worked totally everywhere for the three weeks (both times) we were in japan. Nakasendo trail, Kanazawa, Akita, Aomori, Hakodate and of course Tokyo. Appreciated the inclusion of extra power and cords.
