Product review (2 stars): Very Flimsy Frame!
I'm sure they'll function fine, but these are Super Flimsy and arrived bent out of shape!  These are bad alternatives to the original ones that are dirty but still very much in shape.  I tried to work the bends out as best as I could, but it is still not in very good shape.  Maybe if they were shipped separately and packaged more carefully, they might have survived the shipping abuse.
