When I first bought my set, I thought they were great and solid as hell. Maybe I got the one-in-a-million poorly built wheel, but mine had some pretty significant issues with spoke tension on my rear wheel that became apparent within the third month of riding. So far I've had to have it retensioned twice (had them almost a year now, since last september). There aren't any cracks on the rim or anything else wrong with them that would cause the spokes to loosen up, but twice I 've had spokes come loose enough to turn the nipple with your fingers. That isn't acceptable to me. Hopefully the last tension job I had done will solve this problem, but if they don't, I think I'm going to have thebikebiz build me up some decent wheels and keep these as rain/backup wheels.
While I have been a little dissapointed in the build quality, they have done the job pretty well as far as getting me around, I haven't had a problem with the front wheel, and nobody else seems to have the same problems with them that I do, so maybe it's an isolated incident. I think they are a pretty good value for the price. Hopefully you won't have any issues with yours!
