The ease-of-use and how quickly it has been adopted by our users. We have now migrated over 10% of all analytics queries from our legacy platform. I have no complaints about the product itself - it's easy to use and does exactly what it says on the tin! Pricing is good for initial set up but difficult to justify with ongoing maintenance. Would encourage prospective customers to consider their needs carefully as there are several off the shelf products that will meet those needs very well. Our organisation had previously used SAS, which was hugely expensive and required considerable training and support from a team of specialists. H provides us with a simple to manage and deploy solution with minimal user intervention after setup. This allows time and resource to be focused on solving problems rather than supporting a complex tool.
