Mostly happy with mine (normal Racing 7, not CX), but they did go slightly out of true after a few hundred miles. Very easily sorted with a spoke key but it shouldn't happen.
If I'm being picky I would say that the joint in the rim on my set wasn't particularly smooth. Now I've used the wheels a bit the step has smoothed out. Perhaps not 100% on the quality control, and if I had more time and was buying again I'd look into getting a handbuilt set made up instead. It's made me wary of buying more expensive wheels as if they can't get the basics right I'm not encouraged to spend more with them.
