I have nothing against the product's quality. I think it's a great idea, very beautiful design, very easy to use and overall one of the best products I have seen in terms of quality and design, but before purchasing there are some things people should know about:

1. It´s very difficult to know how to download your changes in html version. It sounds the most important part, right? You make some changes and you download the html docs. Except that it doesn't work like that. After purchasing the product and downloading it, you start making the changes and when they are done and you want to download them, it tells you that "Getting the Html in Demo is disabled" , so now you have to find answer and then you go to support. A good idea would be to make a step by step guide on how to use your product. Your product's page is full of information about features but nothing about how to use them.

2. Support (but this might be envato's fault) The only way to find a straight answer is to submit a ticket. But for that you have to sign in again on their (medium rare) website. A possible solution would be to allow people to contact you directly from the envato's website.

Again, this is one of the best (if not the best) products I have seen in terms of quality and a huge advance for designers as well as non designers. Very easy to use, responsive, good sense of design (space, typography...) That's what makes it harder to see it ruined by a poor execution in terms of support and usability. But again, that might not be entirely the authors fault but envato's fault.
