Despite the price, these slides are very good. They are durable and slide very easily. They have plastic latches so you can remove half of the outer bracket from the sliding components for easier installation. The slide rails are well lubricated. They have good positive rubber stops to keep them from slipping, but require little extra effort to open. However, you can easily remove the stops if you don't need this extra feature. I mounted rails on 3 heavy drawers of the workbench, which now run very smoothly. I've also used them (perhaps overdoing it) on a small tool stand.
