I have used several services to deliver online training / content. I saw ProductDyno and thought it looked clean and simple to set up. It WAS! This alone was a BIG plus. I moved everything over to productdyno and now I actually have a life back.
Occasionally we might have a hiccup, say with an update. But this is fixed DAM fast. Some may complain about this but I look at it differently. If nothing ever changes and nothing ever fails then this tells me that the company has stopped innovation. Productdyno keeps getting better! The company actually listens to its users. We get to vote up suggestions. We get to be part of the process of pushing this software to the top of the pile. I am delighted to be part of continually making something better.
