Product review (3 stars): I've replaces several sets - durability is OK
We've owned our refrigerator for 8 years.  I've replaced the lower door closer 3 times.  I believe it's because our three son's hang on the door while it's being opened and that causes the "hump" on the door closer to grind down to a flat surface.  I've even removed a shelf and items from the inside door to reduce the weight, but closer continues to grind away.  Either the plastic isn't durable, the design is flawed, or the boys hanging on the door continues to be a problem.
