I bought these for the soft close feature and was misled. There's a static plastic part that prevents metal-to-metal contact and what they call "soft closing" but nothing like that. The track still comes to an abrupt, abrupt stop at the end. It doesn't even remotely resemble the soft-close feature I'm used to on toolboxes, drawers, and cabinets from different manufacturers. I rate it so low because my purchase was solely dependent on this feature and it was badly misrepresented.
