Silver WifiBuddy
The internet speed when in LTE is quite fast. However, once you have used up your quota for the day, the service will be downgraded to 3G and the internet speed is unbearable. I couldn't even load Google Map. Fortunately LTE can be used again the next day. Japan WifiBuddy did make a note about the internet quota and internet speed so they are not at fault. If I were to rent again I'd rent the higher tier Wifi Buddy.

Worth every penny.
I would get this again. Even though the advertised speed was not 187 Mbps down. It was more around 20-30 Mbps down in reality. Great coverage. It could be spotty in high density areas but that is to be expected. I really don't think you can do better than this though.

Worked well!
Well, it worked the whole time we were in Japan, we had little glitches due to our old cellphones (+4 or5 years old) but we were always able to get it to work comes with a power bank which was also more than helpful since as we all know cellphone batteries are terrible. In itself the pocket wifi was small and light, similar to a 4 inches cellphone and lasted the whole day. Would have it again. Made our trip a whole lot easier. I mean it.

Amazing. Just amazing.
It was such a seamless process to pick up, use, and drop off. We had no issues with the WifiBuddy as we used it, we had consistent coverage and it was impressively fast. Having the extra charger to use with a wonder as well. Without a question, we will be using Japan WifiBuddy next time we visit Japan.

An Essential Travel Item
Great value for money, made exploring Japan so much easier by having a consistent internet connection for maps and travel info. Was cheaper than international roaming! Battery lasted most of the day with the supplied power bank getting it through till late in the night. Would highly recommend.
