Used these to replace the bearings in my inline skates. Wanted ABEC 3 and there weren’t many offerings on Amazon. Took a chance on this one even without many reviews. Really liked that the spacers were included! Have skated ~15 miles since installing the new bearings, and they’re working great. Reason for 4 stars instead of 5 was because I purchased these twice in separate orders. (2 packs total.) First order that arrived had all black housing for the bearings. Second order had orange housing (like the picture.) Wished they would have been consistent for aesthetic purposes. Needed to install them ASAP (skates take both packs) so I didn’t bother requesting an exchange when I realized the difference. As long as each variety performs the same over time, I don’t expect it to be an issue aside from a visual difference.
