I enjoyed having the ability to have access to their API's and how they could implement them in my applications through python. Also being able to interact with their GUI and using it as a backend for my applications. I didn't like that I had to pay some amount of money each month just for the use of their API's. It was also hard to get help from them if you were stuck. You basically had to learn everything yourself which took a lot of trial and error. They offer a free version but it is limited in functionality. We used this product for creating reports that were required by our customers.
