Reasonable but not always reliable
Instructions were clear and the device was simple to use. Battery life was better than expected and only used the spare battery once or twice. It worked throughout most of Japan, but the service was very spotty and fluctuated at times. Places we expected to have good service were at times unreliable. Overall we enjoyed the wifi buddy in Japan and would recommend the product.

Satisfied customer
I was recently in Japan 10/22-29. My japan WiFi buddy was waiting for me at my hotel upon arrival. Everything was labeled and organized. Easy instructions. Literally just connect and go. The extra battery came in handy multiple times. I guess my unit was overheating, so it was dying faster towards the end of my trip. Always had service (until battery died, but that was an easy fix with the extra battery). The one time I truly had no service was when I was on the ferry on Lake Ashi, but hey I was in the middle of a lake. Easy to return, just handed the package to my hotel concierge. Would definitely recommend to anybody. Will use next time I’m in japan.

Made everything a lot easier
Loved the wifibuddy. It was easy to pick up, it was easy to use and it was easy to send back. It made finding stuff in Tokyo a lot easier and saved us precious vacation time. It sometimes didn't cover places that I think should have internet but the overall experience is that the Wi-Fi buddy is a life saver. Would recommend it to anyone who goes to Tokyo and doesn't speak Japanese.
