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.

Easy to install, discrete and they roll. This is a game changer. Only bummer is the casters are leaving marks on the surface.

Idea behind this is great but the execution is a flop. Hit a crack on the floor about a quarter inch wide. There is no way to fix it so it's money down the drain.

Need better descriptions, very lightweight apparently. It is useful only if it is something that weighs ounces and if you have extra double tape or gorilla glue lying around.
