Preface: I've owned a set of Bones Swiss Ceramic bearings (yes, the $160 bearings) for a couple of years now, so any ceramic bearing I try is going to be compared to my experience with those. Also, I exclusively use them for longboarding, and probably ride between 20 and 50 miles a week on them - that's my base.
Out of the box, I was impressed with these - they have shields on both sides, which the Bones ceramics lack, so I figured these would stay clean for a long time. They broke in well enough, and seemed pretty good compared to the non-ceramic bearings I use. By the time I assumed they'd start getting into their groove, they became dirty and needed to be cleaned.
I skate in the same place all the time (a large local park with 1.5 mile walking path which loops around the entire park), and I don't recall skating through any more dirt than usual. No biggie, I simply figured it would be an interesting experience to now clean them and add the same lubricant to them that I use for my other ceramic bearings (Bones Speed Cream). Once I did that, they were working great again, but, as happened the first time, they became dirty in short order. I don't know what is causing that. I replaced the shields perfectly, it's not like I screwed that up, so... I just don't know.
I really wanted these to be a cheaper alternative to the Bones ceramics, since they're far more affordable, but... they just haven't measured up. I wonder if having shields on both sides allows any dirt that gets in to just start caking within the bearing, not allowing it to escape. I don't know. YMMV, of course. They're not terrible, mind you, just not sure they're worth the price compared to maybe some regular steel Bones bearings. I'll update this review if things change, as I only recently got these (a couple months ago).
