Product review (5 stars): Exact replacement.
I've been putting off replacing this arm for months beacuse I thought it was too hard to do.  Wrong!  15 minutes later and I'm dispensing ice again!  And I work slowly!

It's still a cheap piece of plastic that may fail again and $30  seems a bit steep for the plastic that is.  It is what it is....

It works perfectly and it's definitely a DIY item.
