AMAZING
This service was amazing from start to finish. Immediate feedback and emails to help us pick which level of coverage was right for us, as well as honest advice on how and where to have our device delivered really made us feel at ease. Then the actual wifi was always perfect and for such a reasonable price considering how much we used it! I highly recommend this product and will definitely use it again!

Fulfilled my needs
Very good coverage and data speed for the price. Would have appreciated more battery life but that's what the battery pack is for. Company was very helpful, I had no issues changing the return date when I changed my travel plans.

Good wifi solution
A good price, and good reception in most places. The external portable charger allowed the pocket wifi to maintain its charge for an entire day. The unit sometimes got hot in my backpack, and would slow down a little, but this was solved by taking it out to allow it to cool down.

Silver Wifi
Solid and dependable, as always -- this is our third time renting from Japan Wifi Buddy, our first being back in 2014, and the reason why we keep coming back. Customer service has always been excellent! Trey has done a great job with his crew, as they have certainly grown over the years. The only complaint I have is not really one with the hardware, but with the fact that broadband needs have increased so much over the years that we always we'll exceeded our Silver WiFi Buddy 4G limit of 170 MB a day. Perhaps it's time to now call it "Bronze" (an option that JWB used to have awhile ago), to remind us that this option is really only best suited for VERY light users. Thanks for giving us a great service!
