I like how easy it is to set up, configure & use in your apps with multiple different languages (I used JavaScript). The documentation can be improved but overall very good! We are currently using this for our mobile app which aggregates data from other sources - eCommerce tracking software as well weather sensors etc.. This allows us quickly create new features without having developers build them ourselves or waiting weeks/months before they arrive at production level due delays inherent when working remotely we were able solve problems faster than if had been building by hand alone.
