We needed to refinish our cabinets and the price for soft-closing large drawers was too high. I searched a bit and found them for a good price. I easily swapped out my current slides for these in just a few hours and everything fitted perfectly. I will say they don't slide as smooth as the originals but I expected that and am willing to give it up to have a smooth close without paying a ton. Now my drawers stay closed and don't slide out again when you close them. It takes more force to open them, but that's also expected. The only reason I gave 4 runs is because they don't slide as smoothly as my originals.
