Four of the five pairs I received had an incorrectly installed closer plunger which caused the closer to not work and required the drawer to be pulled out the last inch Made of clear plastic at the end of the plunger there is a guide pin sticking out which should be outside of the gray plastic, not inside. I used a flathead screwdriver to gently pry open the gray plastic and twist the latch into place. If the guide pin is outside, the cushioning may be working properly.
