Product review (3 stars): Retention Clip Issues
It's hard to say whether something like this is actually functional...does it do what it's intended.  Under the assumption that the filter media is equivalent to the original, coupled with the excellent price for a 3-pack, I would have given it five stars.  Fit is an issue, and the reason why I gave it only three stars.  The physical size of the filter body is correct.  Where there is an issue is the design of the retaining clips.  The original filter has a V-shaped clip hinge (the portion of the clip that gives the clip its spring action), where this filter has a U-shaped hinge.  The bottom of the U adds enough to the overall width of the filter to make it nearly impossible to snap it into place.  I pretty much had to force it and wonder how difficult it will be to remove.  If they redesign the clip to make it like the original, I am sure that it could be labeled a great product.
