Perfect for our trip!
For us, it was easy to pick up, easy to drop off, and it made navigating Tokyo so much simpler! I loved how thorough they were about ensuring we had all the information we needed to pick up the device. It never dropped signal; it was super reliable. We'll be going with this company again if we visit in the future :)

Reliable and fast!
I had enough speed to stream, which was my only requirement. This thing never failed me, nor did it ever overheat during the summer heat. This will be my go-to for my next trip to Japan!

Perfect for 3 month stay
As a family of 4 we used this all day and all over Japan without any issues. Make sure you bring the power bar so you can stay connected all day. Worked well for us in Kyoto, Tokyo, around Niigata and Chiba. There was always fast WiFi available!

Excellent Product/Excelent Customer Service
The Diamond WifiBuddy worked great. The customer service was very quick to respond and help me as my travel plans were changed last minute and they were able to get me another product sent to a different city right away

WiFi lasted the whole time
WiFi lasted the whole time that we needed it even with being on our phones for a lot of the day. Easily picked up and dropped off at our hotel, would recommend!
