I've ridden them on my road bike for that last few years.. and haven't treated them well.
5 years on the breaking surface developed a small soft spot so i retired them.
In that time i serviced them once or twice, rode them in the dry wet and took them off road.
Saying that, i did a bit of research and bought from one of the manufactures with a bit more cred, hong fu (frame) and far sports (three sets of wheels)
Be careful of some of the ebay sellers. some of them have some pretty poxy products
Check this forum for some good information.
