Anyone else seen the new C# .NET CommandBars beta from Codejock? I think I like it :)

Question

I was just doing some google searches looking for ways to improve the GUI of my C# app. I stumbled upon Codejock Software and seen they have some really nice C# components. Right now their CommandBars component is still in beta, but I like what I have seen so far. You can find the beta here: http://codejock.com/downloads/

So what do you guys think of this? Should I use this? Any cons to using a third party component?

Thanks
