Product review (1 stars): A box of empty promises!
I ordered these under the presumption from other reviews that the filters had a dust shield and a reinforcement mesh on the inside for rigidity, which is exactly what I was looking for.

Well...what showed up?  A package of 3 of the same flimsy garbage crap Ive bought before and had issues with warping and the cone collapsing.  I don't know why its so hard to only offer the good filters and leave the garbage ones out.
