The app is fast-ish (not always) and reliable. BUT and it's a big but...it WILL translate the original text as well if you are trying to see what a word means. For exaple, lets say you translate a paragraph and you're reading it and want to know what the original word was so you highligh and select to see it (that is a feature of the app). It will show the current translated word and the original but ONLY translated so you will see the same word twice (for example, cocinar----cocinar). It will appear exactly like this and this haappens when the app is set to auto. There is no way to undo this.

The plugin keeps translate pages or selection in English even though I seleceted a different language. For whatever reason, a couple of reloading the page enables it to work properly and translate in the chosen language which is still quite annoying. Other than that it's great and deserves 5 stars. But it's a huge downside.

The full page translator website google offers (but makes increasingly hard to find) sometimes doesn't load the images on a page, and it's not ideal to have to find that website every time. I'm a safari user because it's the browser with the lowest impact on my system, and this integrates well.

I tried a few other apps claiming to do what this one said, and it either came back with and error page or didn't work really well.This does exactly what it says, translating very well from Korean and Japanese to English almost instantly when I click to do so.
