Amazing!!
Would have struggled navigating tokyo if it wasn't for the wifi buddy. Worked great, easy to pick up and easy to return. Definitely would use again!

Best idea ever
Great service and product, internet worked perfectly and super fast. Needed recharging towards afternoon/ early evening but the accompanying portable charger was helpful. Delivered to our hotel with no problems.

Wifi buddy diamond
The customer service here was wonderful, they ship it directly to the airport, hotel, or even air bnb that you are using. We chose airport, they gave us a map of the floor that the post office was on, and all the information we would need to get it. Inside our package was one Wi-Fi device, an external battery, chargers for both, an already stamped envelope to return the Wi-Fi, and an instruction card. Gps can be a little spotty with Wi-Fi hotspots, had to make a few u-turns. And the battery seemed to die at peculiar times, must be what the back up batter was for. All in all a great service.

Easy and Fast!
We used our Diamond WifiBuddy for 2 weeks while in Tokyo, Osaka, Kyoto, and Arimaonsen. It had full access the entire time in all the locations that we visited. We had up to 2 phones and 2 computers synced to it at a time and we didn't notice any slowdowns. Battery life would take us through mid afternoon depending on usage, but the portable charger would easily take us through to the evening and late night. Overall it was a solid portable wifi and easy to pick up, set up, and return!
