Product review (4 stars): Convenient replacement and works well
Purchased this replacement when the plastic sleeve failed on the ice bucket originally supplied with the refrigerator.  Based on several reviews suggesting that attempting to replace only the plastic sleeve was marginally successful at best, I opted to replace the entire ice bucket unit.  The new unit is a direct replacement and works well.  A benefit is that the new unit also has new chopping blades which improves crushing of ice with less resistance (one reason sleeve likely failed over time).
Only negative is the price - as with any replacement part, this is very expensive considering it is only inexpensive plastic and metal components.
