The two things that impress me the most with RubberDuck, it always works well without worrying about maintenance and security issues, and of course the ease of use is out of this world.

I can now offer my SMB clients a high-quality professional website, at very low cost. Around here, most agencies offer only WP websites that are way too complicated and pricy for what SMB use them for.

RubberDuck has allowed us to cut the development time of our websites in half. It's a FormulaOne not just for building websites, but also for loading speed and even customer support response time.
