We do not sell products as such . We offer services e.g. language classes , tuition , translation , proofreading , interviewing , recruitment and accent training.
However, we do recommend some good course-books and some other language products such as electronic dictionaries.
A list of recommended products is currently being compiled.
A Franklin translator (expensive though it maybe ) is a fantastic resource for travellers. I used one 10 years ago (it was good even then). But things have moved on and the dictionary has literally millions of entries and reads the words aloud in both languages.
