Great service and device
The device was delivered to my hotel in Shinjuku and was easy to set up and ready to go. It was wonderful being able to use it all around Japan and not get lost and find restaurants. At the end I just put it back in the return mailer and that was it. I would use WiFi Buddy again.

Fantastic service!
Picked up my two diamond WiFi buddies at Haneda after hours without issue. Both WiFi’s worked great with strong connections and even better bandwidth. After two weeks throughout the country, our group of 5 measured about 75gb between the two WiFi’s. This was with heavy navigation use, audio, and video streaming. Battery life was also great and with the diamond package, we also received the extended batteries. Never had any issues!

AWESOME experience
Rented my WiFi and had it delivered to my hotel in Haneda Airport. When I checked in, it was there waiting for me. Easy to hook up and not once did I have any problems with it. Very Satisfied. I recommend WifiBuddy and will rent from them again.

I didn’t use the back
I didn’t use the back up battery because I didn’t know how it worked . So I really didn’t use it to the max. Also my phone battery went really low around 2 pm (5 hours of use). But it was good to have. It was very convenient to pick up and return.
