Product review (3 stars): Good replacement part for a shoddily engineered product
It will work just like the plastic replacement that preceded it..poorly but for 7 years.  Overpriced and underbuilt but four stars are the only alternative as the $1000 replacement that would have junked out 7 years from now would have been no better.  Added washers to the back of the spring activated bolted attachments so perhaps it can distribute the stress of constant up-and-downs for a few years more.  A fine (and only) fix for a poorly designed piece of equipment.  The only thing the manufacturer could possibly do other than hang their head in shame is to discount their shoddy replacement part.
