Yes, I have them and like them. The 6 pawls make for quick and secure engagement. They are super stiff and light. I am only 120 lbs, but they are available with a variety of rims and spokes to match your needs. They also require a periodic spoke tension check which is nothing in time compared to maintenance on mavic hubs. I have not had any problems, but from my email inquiries, customer service seems to be pretty good.
...and then there are the colors. It's like going to a candy shop.
