Interest limited without the CD

The book is very well done, making us work on various topics, travel, daily life and work, etc ..
Each chapter contains a vocabulary and grammatical part. Content is neat and pleasant to follow.

Big downside, many exercises refer to the audio CD that is not included with the book.
It is sold separately but currently extremely difficult to find and very expensive.
This limits strongly the interest of the whole.

In conclusion I would not recommend the purchase, making other editions as well and complete, for the same price.
