Diamond Wifi Buddy
Good coverage and didn’t have any issue during our 3 weeks in Japan. It was delivered to the Hotel directly and return was easy, just drop at the airport postbox. Highly recommended.

Fantastic!
21 day’s of worry free, high speed internet for our 3 devices. Such good service and connectivity that we never bothered to use any of the free wifi connections we were offered any place else! The set was waiting for us at Narita and we dropped it off at the airport on our return—couldn’t be easier! All this for a capped price...We will definitely use this again when we go to Japan again!

Good service and (almost) as expected
Good connection and speed everywhere I went, smooth delivery and return procedure. Picked the unit up at Narita post office and returned it to the same place with the supplied envelope. One minus though: the unit arrived with depleted battery, and I had to connect the supplied external battery right away. As I arrived in Narita in the morning, I was out of power before I reached my final destination late in the evening.
