Great service. Battery can improve
The service works great. We had connection everywhere we where at Japan, the connection speed is great as well. We were able to stream in Twitch and sync files at the same time, and everything worked fine. Having the device delivered to our Airbnb was good as well and returning it at the airport is super convenient. The only downside was that the battery of the device didn't last as much as we wanted to. We have used other devices half the size of this one, and their battery lasted much more. But Japan WifiBuddy also provides an extra power bank, which was convenient. It was just something extra to take care of. Apart from that, everything was very good.

Great!
Works very fast, battery life was adequate. Internet wasnt lagging, only thing I didnt like was the device slightly heats up so must keep an eye on.

Met our needs
Reception throughout our travel in Japan was good. Only issue was the pocket wifi cannot last for a day, had to recharge using the spare battery that came with the kit.
