Comments: Junk. The most important thing about a bearing in my opinion is how fast it wears out. These wore out _really_ fast. I will not be buying mission bearings again... and in general I like mission equipment but these bearings stink.

Comments: I love these bearings. I play outdoors and have only had to clean them once in the last month an half. I play 3-4 times a week so that's pretty impressive. When they do get dirty or stop spinning all it takes is a quick wipe down and some fresh oil on the bearing with a quick spin to get them back to spinning like new. I'm going to buy another set for my indoor wheels.

Comments:Been using these as my indoor bearings for the last 2 months and couldn't be happier. They are smooth and fast and a big improvement on the mission abec 7's that came with my skates. If they are loud and stop spinning, sounds like they need cleaned. No bearing will survive getting sand in them from playing outdoors without maintenance. These same bearings were selling for 55 at my local pro shop, great deal here.

Comments:I bought these because they were cheap and I needed some outdoor bearings. It's nice not having to change out the bearings every time I change from my outdoor and indoor sets of wheels. These bearings suck though. After a few outdoor sessions they got really loud and most of the bearings stopped spinning. I still use them for outdoor because we play for fun, but I would never use these indoor. They seem pretty good for the price, but I would've never bought them if I knew they were this bad.
