The best thing about this software are that it's very easy to use as well its free! I like everything in particular how fast you can train models using their API integration with AWS services such us S3 or RedshiftDB (or even GCP).
There was nothing really negative at all so far but maybe more documentation would be nice? Maybe also an easier way of installing packages could help people who don't have much experience regarding python/pandas etc.? Try out if your interested because there isn’t any other tool similar enough which provides great support via email too when something goes wrong :D Data science tools should come up first time around otherwise they won´ t get used again ever since we need them every day anyways :).
