Will purchase again on our next trip. Totally satisfied.
Aside from while driving through a few tunnels, we had service all of the time. The speeds were fast and better than the WiFi at our hotel. The included power bank was a great addition as although the battery lasts quite awhile, if you're out all day you will need it. Returning the device is easy just make sure you try to make everything lay as flat as possible in the return envelope or you'll have issues getting it in a mail slot. Highly recommended.

I made a huge mistake, but Japan Wifi Buddy saved me
I inputted the wrong flight info and realized that I couldn't get my wifi router when I had landed. I contacted Japan Wifi Buddy and they were super helpful! They were able to reroute a router to the place that I was staying during the trip! The router worked perfectly and excellent while we were in Japan. The router lasted most of the day at Disney Sea and needed a quick recharge from a portable battery charger. I think it needed a recharge because we were inside the rides (no signal) and it was using a lot of power hunting for a signal. All of the other days we never had battery issues. Thank everyone!

Best Portable Wifi ever!
The Diamond Wifibuddy was awesome, easily the best decision we ever made!! We never really had problems with it, aside from it being a little easy to overheat. But it was never an inconvenience for us! We loved how we basically had connection everywhere and how good the battery life was. The instructions given on how to use it and mail it back to you guys was easy to understand, so that was appreciated! Also, we felt very supported from the prompt responses to our emails. We will definitely be using the Wifibuddy service again next time we go to Japan!
