Great battery life and extra cables, but performance was not to good.
I rented the Diamond WifiBuddy for 21 days when in japan, Easy to setup and use, great battery life, extra cables and battery. the only down side is that even though its the "Diamond" WifiBuddy I never saw above 25mb/s download speed (tested in open area, on top of buildings, on top of mountains, in the train), because of this I could never do (reliable) video calls with family overseas or watch high quality youtube videos (luckily most hotels have good wifi). maybe an optional antenna that we can plug into the "antenna port" on the device to get good reception (speed) when needed would be cool.

Don't travel without WiFi!
The Platinum WiFiBuddy was perfect for the two of us during our two-week stay. It's an excellent, stress-free way to stay connected no matter where you are!

Good service for a good rate
The pick up (Narita Airport Post Office) and drop off (same post office) was extremely convenient. The hardware itself was small and compact so easy to carry around. There were times when the wifi was weak or did not work altogether but generally speaking, it was fairly reliable.

Fantastic!
Our signal worked 95% of time and it was fast. I wish we could do this all over the world. Only place it didn't work was when we were in remote area called Naruko but then it was okay rest of our 2 week trip.
