Thank you! :)
I enjoyed using the Diamond WifiBuddy. Thank you to Ri for making one more available when the website said there it was sold out. I like the extra powerbank which came in very handy. I also liked everything else about the entire package: the small pouch for the wifibuddy, 2 sets of chargers and cables, a laminated instruction card to remind me of what to do, a larger pouch to contain everything and lastly the return envelope to mail everything back when I'm done. This is my first time using a wifi service in Japan and JapanWifiBuddy is simply awesome. I look forward to using the service again on a future visit and would definitely recommend it to my family, friends or anyone who asks about my experience in Japan.

Wonderfully Easy
This was the best thing ever traveling Japan! We were always able to get connection and also stay connected to each other. The first day it overheated after a couple of hours since our trip was in September it was still pretty hot out. After that I made sure to keep an eye on it and check it every so often to make sure it was ok. I wish there was some sort of cooling bag that I could've put it in to keep it from overheating. The battery life wasn't the greatest but I just made sure to keep it plugged in when it needed to be charged. It was also very easy to ship it back with the envelope provided.
