AutoML platforms - for non-ML practitioners?

Does anyone have experience developing and operationalizing ML models using most popular AutoML solutions like DataRobot, BigML, As the AI/ML product manager for my company, I decided to have the data scientists of AI consultancy I hired use H2O as a productivity enhancement tool and allow me to better monitor and manage the work effort. Initial response to my request was not enthusiastic but I made a condition to work with them as outsource company.

Would appreciated hearing about these types of tools and their practicality, challenges etc. Thank you.
