Worked just as described - I wish the battery lasted a little longer
We traveled to Tokyo, Kyoto, and the Five Lakes region around Mt. Fuji. The wifi was great and quite fast except a little spotty in the five lakes region (pretty rural area so it was to be expected) I traveled with my wife, and we both connected only our phones. We would usually start using the wifibuddy around 9am and around 6pm it would die. Luckily they included an extra battery but it would have been nice if it lasted all day on its own battery. Overall in two weeks we used just under 20GBs so I am not sure if that is heavy usage or not.

Good Product and Great Coverage
This the second time I've rented a Buddy. Excellent coverage everywhere in and around Tokyo (which is to be expected). The battery drained faster than during my last rental, but all in all a good value.

Essential throughout our trip
Japan WifiBuddy worked everywhere we went in Tokyo and Kyoto and was indispensable as a navigation and information aid throughout our trip. Highly recommend!

Platinum WifiBuddy
Very useful and worked very well while we were in Japan. Good battery life frequently lasted all day. Seamless pick-up and return process. Occasionally lost connection despite only visiting major cities but these moments were brief and we were connected the majority of the time.
