Great device to have when traveling
Very happy that we rented this Wifi Buddy for 10 days in Japan. It worked quite well. We were with a tour group so really did not need it for maps or directions. However, it was quite convenient to have access to wifi while on our bus or on the bullet train. Even some hotels had slow wifi connections so it was great to have our Wifi Buddy. I would sometimes turn it off when it was not needed for fear of running down the battery. Maybe it would have lasted all day? Not sure. The device was waiting for us at our first hotel and at our last hotel I put it in the mailing envelope and handed it to someone at the front desk. Rent one, you won't regret it!

Very happy with Silver WifiBuddy
We rented a Silver WifiBuddy for 1 week. It was more than enough data for the light browsing and navigating we did while away from our accommodation. Picking up the portable wifi from Shinjuku post office was a breeze, as was dropping it off at Haneda Airport. We received excellent and personal service. We would definitely repeat our rental if (when!) we return to Japan.
