2 person 2 week trip with Silver
Although the wifi was a bit unresponsive/slow at times, restarting the device generally fixed it. Having wifi throughout the trip was super helpful. Big thanks to Ri for helping with some logistics in shipping the device. This is my second time using this device and it's fully met my expectations both times. Definitely recommend!

Fantastic Device for Travel
I used the diamond wifi buddy for an 8 day trip in Japan and absolutely loved it! The speeds were great, my only issue was that I would sometimes need to reset the device because it would lose signal, but that was fairly rare (maybe 1 time a day) but for the price it was a fantastic value and made the trip go so well!

Essential Traveling Gear
The device was received at a convenient location in my arriving terminal. Our party of 3 had uninterrupted wifi access throughout our 12 day Japanese adventure. This included some remote locations, trains, autos, subways, hotel rooms, and wandering about the cities. We had several high-capacity batteries (not included) which ensured we never ran out of juice.
Device was easy to setup asnd provided fast internet access from our smartphones.
I found this service a great value, total cost was less than 10 USD per day.

Excellent product - Great Service - highly recommend
I recently returned from a great trip to Japan which would have been extremely difficult if it was not for renting a pocket modem from Japan WffiBuddy. Very easy and simple to order with the modem being delivered to my Hotel in Osaka. I then used it for over two weeks of traveling. Signal was always very strong as was the coverage. JapanWifi buddy supply everything right down to a rechargeable extra battery and a fully addressed envelope to return the modem to them. Its easy, reliable and I highly recommend them and the product.
