I really like the fact that standard windows icons are provided with the NOV Ribbon example, avoiding the need to recreate the wheel and giving a more professional appearance. Using the provided Visual Studio NOV solution, it is fairly straightforward to add custom icons with a few extra simple steps. The gallery of C# examples for all controls makes it easy to create custom layouts. For the handful of customizations I could not find in the examples or user forums, the tech support responses got me going within a day.
