Good Service, Died Often
We had our WifiBuddy for a one-month trip around Japan. Having a pocket wifi is an absolute MUST - which is why it was frustrating that our pocket wifi often died after only 5-6 hours of use, when we were out for 12+ hours many days. It came with a portable charger that was terrible and would only charge the wifibuddy for about 20 minutes before dying, so we just used our own portable charger that we brought. HOWEVER, we found that the wifibuddy had excellent service across all parts of Japan, even the rural places we went to. It was also an excellent value with prices about half of what other companies wanted to charge. Overall, it was a good value and I would rent again. Just make sure to have your own portable charger, with a large capacity, to charge the wifibuddy and your own devices!

Great Product and Company
We used our WiFi buddy for two weeks while we were in Japan. Everything worked great. We picked it up at the airport post office when we arrived and dropped it off there when we left . Everything was super convenient and a great price. This is our second time using it and we will use it on future trips too.
