Very useful and easy to manage

It is a very good prepared delivery with device, battery and charger and easy to manage with an envelope to send all back. Good product and very professionell service...

Don't think it twice

Just get it, it's a must, absolutely necessary and top not quality. Streaming while over the shinkansen? Not a problem! 110% recommended.

Reliable and easy

Rented for about 2 weeks and was very reliable and was efficient. The battery lasts maybe 5-6 hours so I loved that they included portable charger along with the portable WiFi. I rented from a company in another country and they do not automatically include portable charger. Thought the price was very fair. The pickup and drop off was very easy and efficient. Would use them again next time I am in Japan.

Great Product and Service - small issue

I rented a Diamond WifiBuddy for our group of four travellers. The hotspot worked flawlessly, easily handling four simultaneous streams. Wifi was fast and worked inside many buildings and the subway. Pick-up and drop-off worked flawlessly. The only issue that we had was that the supplied external battery did not work. Luckily we were travelling with our own external battery and used it to charge the unit instead. (The battery in the unit typically lasted about 10 hours with heavy usage.)
