It works well with google and bing, but yandex translation is totally wrong, and absolutely different than the official yandex translate page and tools.

Worst tanslator ever especially for Turkish.
Needs to update the translation engine or use Firefox translator.

It works pretty well, but lacks an option to set an original language. It'll often try to translate words from ðe wrong language and give me an inaccurate translation. Being able to set a language to translate from would fix ðis.

It's a 5 star extension that works great, with one major flaw: an annoying icon appears automatically each time that I select some text, it can be disabled from the toolbar quick settings, but is nowhere to be found in the main settings. Will give it 5 stars again once this is fixed.
Should also allow for once in a while donations.

No issues at all so far, it's much better than the Chrome's Always Translate feature, which fails to translate certain texts including Twitter posts, this add-on TWP translates everything so far including Twitter posts that Chrome fails to do. I highly recommend this extension so far, I hope it doesn't disappoint in the long run and will definitely be donating if it stays this good.

Cons:
- Doesn't translate Google maps.
- Doesn't translate images (don't think this is possible for an extension though).
- Doesn't translate automatically sometimes (refreshing or pressing the button fixes this).
- Doesn't translate background tabs.

Edit: Noticed that subtitles/captions for sites (YouTube for example) become mixed, some parts of the text is not translated while some are, preferably it should all be translated, or not translated at all.
