The translation is indeed very well done, staying very close to the technical terms used, without compromising the understanding of the text. It maintains the layout and arrangement of the text. Reliable. Excellent quality.sergioBrazilRated 5 out of 5 on TrustpilotThis app has been a game-changer for translating books.
