I have made multiple purchases of these filters and the filters themselves have been consistently fine--they fit into the casings well, filter well, etc. The holding pin oftentimes takes some time to wear enough to easily insert fully.
However, some filtersarrive with the metal mesh sleeve (helpful for reinforcing the filter mesh so it doesn't tear or separate from the plastic housing) and some do not. Disappointing, of course, when they don't.
