I cheat and use them in my quad skates. They are easy to clean, run smoothly, and seem to get better with every session. I am antisapating a having them for a good long time.

Extremely fast but questionable durability

They are very fast, the quality that they were built with make these bearings faster than swiss 6 that i used. The durability is the main problem if you are doing bowl i believe you will be find but since i do a mixture of bowl and street i believe the constant pressure made the bearings of one of my wheels just explode after a couple months of use. Maybe it was faulty equipment but i was extremely careful inserting the bearings into my wheels even used a bearing press. Overall they are the fastest i have used just worry about the durability.
