Good replacement for my Prusa MK4
I broke one of the new bearings when assembling the printer so I purchased these as a replacement. You can feel a difference between the originals that feel more qualitative compared to these bearings but the one I replaced it's on for about 6 months and had no issues.

Worked as intended.
Be careful as several very small ball bearings fell out of one of them when mounting it on the rail. Only slight issue is that there was a little play (a bit larger than the shaft they were on) that worked out ok when I mounted two of them in my carrier.

Smooth but a little noisy
It’s much smoother now and the prints are cleaner. You can hear the ball bearings rolling around and my plastics bushings were quieter. But with all the fans you dont hear it that much louder. I took it apart and put a small amount of grease in it. I hope the seals on the ends dont drip. I’ll edit this comment if I see a problem, but it did quiet it down a little.

Balls pop out like popcorn kernels.
This is no than the dozens of other cheap brands available. It's got the same exact issues where the balls will pop out if you look at them wrong. It works fine other than that, just don't be fooled into thinking this one is any better.

Fit and worked perfectly
Fair price for the quantity (though I only needed half that amount). They appear the same as what's in my Prusa Mk4.
