Easy to understand, configure, and use
I would recommend it. IBM has several other solutions that can connect to it, so no need to buy different pieces from several providers. If you want to find a good solution for the customer and put some translation tool or machine learning for text understanding and so on, you can get this from IBM. It can be a one-stop shop for a good solution. I would rate this solution an eight out of ten. It has good quality, and it's easy to work with.
