I've owned a set of these for about 2 years I don't skate much and don't make 10 stairs gaps but for my needs i.e. cruising making some small gaps and flips these bearings are just superb. They just keep on rolling! And I've got absolutely no problems with them. I had PIG wheels Ceramics before also great stuff but these VXB are faster and smoother well easier to ride no matter if it's raining or not!
