Quality corresponds to the price. 4 out of the 6 linear LM12UU bearings I ordered are working great while 2 doesn't. These 2 are not moving smoothly but instead they feel like there are little cubes in them instead of balls:)
Recommended, but you should take into account that according to my experience you should order 50% more then you really need, so you have some room for the ones that are really low quality.
(Still these are better than the ones I ordered from Ali but truth must be told these
cost 150% more...)

Fit well with the 12mm rods I purchased at the same time
