After trying several professional themes out there for my website, I'm happy I found Icy. The design is stylish and efficient, but most important, very easy to use. Everything that I've needed to stylize (fonts style and sizes, colors, sliders, etc) I've been able to tweak in their no-brainer theme options panel, and with my minimal CSS skills, their prompt support has helped me tweak the theme design to develop my brand.
Overall, I couldn't be happier with my theme. Also, kudos for letting me try a demo version before purchasing.
