Very reliable, good battery life, but slow (2 people)
It's a bit slow for 2 people... forget about video streaming or anything like that. However, we mostly used it for loading directions in Google Maps and looking up reviews for restaurants and other places and it worked fine for that. Very good reliability, had service in Tokyo, Hakone, Kyoto, Nara, and Osaka and on the bullet train/subways.
