Must have for Japan trip
I was in Japan for 12 days and this service was amazing for me. I did not want to tie myself to public internet connection and hotels so i decided to rent this device. No connection issues, enough battery life with powerbank. Everything was smooth. I would recommend everybody who want to visit Japan.

You Really Get More Than What You Pay For!
For those of you wondering if the Diamond Wifi Buddy is worth the extra expense, let me just say: YES! Having unlimited data can give you a peace of mind if you especially have to Facetime, Kakao, Line, etc. anyone anywhere. I also played some Switch online (Splatoon 2) while relaxing and the Diamond Wifi Buddy did a better job than the Wifi at the places I stayed! Watching Youtube on my train ride to Hokkaido was also smooth and of excellent quality! Trust me, you will not regret going Diamond. I only paid about $60 for an 8 day-ish trip. And I paid only $90 for a previous 21 day trip.

Quick and efficient
Thanks for letting us use your wifiBuddy device. It was extremely useful for the short stay my mother had in Japan to stay connected at all times with her family members abroad. Highly recommend your service. To get the device and to return was very efficient.

Great addition to our trip
Having our Japan Wifi-Buddy was a super crucial addition to our recent trip throughout Japan. Delivery/return was easy. For the most part, service was smooth and fast! My only complaint is that the battery died more often than I would've liked, but as long as your bring the external chargers and keep those charged up, you should be okay. Would definitely recommend!
