Product review (5 stars): Sturdier, easy replacement
Took 30 minutes to replace the old pair with the new pair.  Seems a lot sturdier.  The stainless steel screws are torx, and they include a small adapter, but grab a torx set of bits if you have them.
The pictures are hard to read in the printed directions, so use the online video if you can.
The part that had broke on my old one is still plastic, but has been re-engineered as a sturdier piece.  Hopefully I won't have to deal with this again.
