Changes directions smoothly. Unlocking them can take a lot of force. I usually whack the lever with a mallet and that does the trick. They are economical compared to other 3-inch casters.

They roll effortlessly and very easy to install. Aligning the mounting holes to use a single bolt (versus a screw on each side) takes a steady drill hand. Fit wood crib as replacement for old. Worked very well.
