The idea convinced: Read summaries of books, save time and still know everything. Great idea .... The implementation is questionable: First, there are currently very few areas and, accordingly, books (it is advertised with +400, so there are less than 500), on the other hand it is very questionable because who really sums up: Has one who really worked out the most important thing? Has he overlooked things? Does he have relationships in the abstract alienated or misrepresented ?! All things that you only times must let them stand. I had the feeling that the summaries that I have read (How to Win Friends, fast and slow thinking, the Harvard strategy, make it stick) were not very successful.
Trial 3 days very pleasant, more difficult to find the prices is. A link to the English side at the end of the license agreement then brings certainty: 3,49 € per month for a twelve-month subscription is the best and probably goes to several times to check all available titles by. It makes sense maybe 1 month, but the cost already € 6.99: A little bit too much in my opinion.
