I had no idea how much of a difference great bearings made. My old ABEC 9 bearings are like a yugo compared to these. After using them one time I ordered up a second pair so I would not have to switch out my bearings when I changed wheels (Radar Devil Rays) due to changes in the skating surface. I will never go back to anything less than these.

I AM GETTING THESE BEARINGS IN MY LUIGINIO ATTIDUDES AND I HAVE TO SAY THEY LOOK AND SOUND AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! CANT WAIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I upgraded with these from Bones Swiss about 1 1/2 years ago. I really could not tell a difference between the two. My 1st upgrade was from ABEC 3 to Bones Swiss... HUGE Difference! I have destroyed 4 Bones Ceramic bearings since the BONES-TO-CERAMIC upgrade... where as I never damaged any Bones Swiss bearings. Yeah, Yeah.. I am comparing the two. Truthly speaking, I will eventually down grade back to Bones Swiss due to the difference in cost $$$$ is and was not justified / felt / experience between the performance of these two type of bearings. On any note, Bones Ceramics still gets 5 stars.

best bearing 5*****

there the fastest speed bearing ive ever used
