What do you like best?
The best thing I liked about it was its simple Graphical user interface with no advertisements and everything placed correctly on the screen. One can easily look for what he needs on the screen.
It offers millions of flashcards already created by its community users like students and instructors from all over the world. It provides various activities for studying which makes it easier to learn the data at a rapid pace and at the same time not getting bored by using a single platform for all the learning.
It provides labels to categorize various courses and study the specific ones at a time.
What do you dislike?
As per my understanding, It is basically a platform for individual learning and not made for Group/Enterprise learning. There is very less interaction between the users. Also, it is similar to the concept of Wikipedia and may have some information which is already obsolete or modified.
Recommendations to others considering the product
It is a fantastic learning platform. But do remember it has a limited database and you won't find everything here. So, it is for learning the basics of a particular topic you are interested in.
What business problems are you solving with the product? What benefits have you realized?
I have used it to learn the French language as I had to travel to France in a month's time and found this platform to learn the same. So, it helped me in gaining knowledge about a different language.
I also read it sometimes to do my basic learning on Science subjects.
