Everything was perfect! From the
Everything was perfect! From the out of hours pick up at Haneda International (I recommend this even if not out of hours, as all you have to do on arrival is go upstairs to get it, bit take a bus to the domestic terminal like the others...), to the fact that the device was charged from the start, to the simple straight forward instructions, to the instant full coverage, to the length of the charge and the extra spare portable charger! Communication was quick and easy, and when returning, the poping it back in the post box BEFORE going through couldn’t have been simpler. This is definitely a must for anyone coming to Japan. It may be a little more expensive than the other companies (which I have also tried) but this service is 5 star! I will definitely used them again, and recommend too! Thank you to Japan WiFiBuddy for providing an efficient wonderful service.

Helpful
It’s definitely helpful. It gets super hot around mid day then dies. I only recommend 2 people to use it at a time instead of 4 because it gets really hot and dies faster when ego is being used.
