What do you like best?
Love the direct integration with Salesforce to visualize my data in complex ways. I can stylize my data in any way imaginable - just a little bit of effort involved to set it up the way I want it.
What do you dislike?
The recent releases have made the tools more user-friendly, but about 6 months ago you did need a working knowledge of JSON in order to import and shape your data the way you wanted. Now it is much better and is almost entirely point and click.
Recommendations to others considering the product
Einstein is pricey, so make sure you're going to use it. The tools are incredibly powerful and can save a lot of administrative work. Hire a firm that's familiar with the product to help you make the most of it. The ways you can see your data displayed are limited only by your imagination, so basically if you want to see your data a certain way, you can do it - just work with your team to figure out what you need.
What business problems are you solving with the product? What benefits have you realized?
No more manual report generation or cumbersome Excel spreadsheets - I can see all of my data in one place and slice it how I want it.
