Terrific Device!!!
Used the Wi-Fi for the 17 days in Japan and it worked flawlessly. I used the unit and left it attached to the extra battery throughout the day and recharged the extra battery at night ... we never ran out of power. It worked everywhere and kept me connected to the web to be able to use maps and guides and allowed me to use my phone with the internet easily. I plan to use this Wi-Fi from now on, where ever I travel around the globe. Thanks very much for your excellent service, ease of use, instructions and packaging for return.

My WifiBuddy
I rented the Silver Pocket and it was so easy. Ordered online to have it delivered to my hotel. It was waiting for me at check in. Had WiFi connection throughout my two week trip. Return was simple, just had to put in the self postage envelope which was provided. Gave package to registration desk at check out. I would definitely use this service again.

Fantastic wifi - thank you
We had the Diamond WifiBuddy for a month and we were very happy it. We had no problems at all. The battery did go flat by late afternoon but we were provided with a portable charger, although rarely used it as most of our travelling was done by day and by late afternoon we didn't need it so much. Would happily recommend this to anyone and will use again next time we are in Japan - thank you.

Worked perfectly
This was the second time I’ve rented a portable WiFi through this company and everything worked perfectly. The WiFi was waiting for me at my selected pick up location (Narita Airport post office), worked flawlessly during the trip, and sending it back couldn’t be easier. Communication with the staff is always very friendly with a fast response time. I plan on using this service again whenever I travel to Japan.
