I'm a designer who knows just enough to navigate around basic code and their (Designmodo) products are top notch both from a design & UX perspective and from the simplistic implementation of the backend coding.
I've used almost all their products in multiple iterations of releases. You can easily create a top-notch looking website in a matter of hours. The generator app which allows you to build the general layout and sections of your website is awesome. You can then export the code and have a great starting point to tweak and customize your website to your hearts content.
Customer service is also very good. They often respond within minutes of your questions via their live chat feature. Being a person that is not a developer, I often ask very basic questions which I would assume most developers know but they are always willing to help me every step of the way.
