    • Put in my 3D printed car wheels.
I used these in the wheels of some 3D printed cars I made for the kids. They don't spin as freely as advertised, so I sprayed them with WD40. I think they use thicker grease in case it's used for other applications.

    • Good bearings. Just not fast or free spinning.
Good bearings. Have a lot of drag tho. Not low resistance bearings. Just smooth.
