I bought these filters to replace a 650. In terms of quality, these filters are still comparable to original accessories. In terms of editing, it seems to me they are superior to the originals with one caveat. They are superior to the original accessories in that although they require a little more effort to install and remove, they also fit better once installed. The caveat just mentioned is that, as other reviewers have noted, the dust box is harder to snap into place with one of these filters and can fall out during use. With a little force, however, the dust box can actually be used safely again. It doesn't bother me, but some may find it unsatisfying. Overall I am happy with these replacement filters.
