Top marks from WifiBuddy
The Diamond WifiBuddy was already there when we checked in to our hotel with all equipment and return envelope present. The WifiBuddy delivered great speeds and even limited connective whilst we were on our cruise ship. Battery life was very good with two devices connected for most of the day whilst walking around Tokyo, using Google Maps for walking and train directions. Backup battery have a good charging ability and kept the WifiBuddy running when the internal battery was exhausted. Overall, would definitely rent again

Fantastic value
It was very convenient to have our own wifi in Japan. Service was spotty underground sometimes but overall great in Tokyo, Kyoto, Osaka, and Nara. The price was great for 2 weeks of use.
