What do you dislike?
It still suffers from few bugs, for example, the neural network output function is not synchronized and it took me so long to discover that as no the error was not clear. It might not be a good option if you want to use it in a large scale project as my imperssion is that it is still under development.
Recommendations to others considering the product
