What do you like best?
I like Duda's Website Design Editor Tools the best. There are enough choices, in many different areas within the process of designing a website, that you will find just about all that you need to give your website designs the features and functions that you want. And with a little ingenuity and creativity, you can figure out your own solutions to use what they have provided to creatively manipulate what's there in order to achieve the desired effect and results that your project may require.
What do you dislike?
My only issue that I would like Duda to develop further would be an overall "map diagram" which shows where all of the many different options and great features that they have included with their Editor, are located. There are many menus, sub-menus, etc. that a complete diagram showing the connecting "routes" or paths that the user has to navigate to find some of the more illusive settings and more refined details, can be found to avoid the time it takes to search for a very specific item that your website needs.
Recommendations to others considering the product
If you are looking for an intuitive and relative straight-forward way to build a client's website, convert an existing website into a responsive version, or want to manage a website's statistics and usage with a very small learning curve, then I highly recommend Duda to you. Duda has created a no-nonsense, professionally competitive way of competing with the many different available website development programs that exist but most importantly, it has made it also fun!
What business problems are you solving with the product? What benefits have you realized?
Converting clients existing websites for responsive devices like mobile iPhones, iPads, Androids, and many more. I started using Duda's propriety program nearly 3 years ago, back when converting website for responsive applications was still pretty new to the average website designer. Duda's tools at that time were still in their early phase of development but even so they were intuitively designed so that even a designer with a basic understanding of the process, could use them with very little difficulty.
