I love how easy it was, just copy paste my text into flash issue and publish as PDF or HTML file! The only downside would be that you cannot preview what changes are going live before publishing but this will not stop me using the tool again because of its ease-of use.
There's nothing much i dislike about the product other than maybe if there were more templates available with different themes/colors etc., which could make creating newsletters easier. Using flashissue allows us at work to create our own customised newsletters without having to spend time writing them ourselves.
