Lo amo totalmente! xD He aprendido mucho, me sirve mucho para leer los kanjis y trae referencias del libro de heising. Recomendado.

This is as helpful as it is annoying :D it is quite necessary though for learning Japanese, but just, really, really annoying.

This is one of the most useful extensions I have ever come across!! It is really helpful for those who want to learn kanji over the internet.

This thing blows, gonna go back to using firefox because at least perapera japanese works. Mega long delay when trying to turn it on and have to fiddle with it on and off before I can finally get it to work showing popups. I thought a previous update was suppose to fix this.

It's great and useful, but a bit glitchy. I wish they fixed the bugs.

Amazing... if you have issues read the controls to define where it pops up.

Es muy útil para aprender y entender kanjis sin traducir toda la oración. Esencial para estudiar japonés.
