Product review (1 stars): Why did they change the design???
This latest version was slightly different than their previous version which I had purchased. The difference was the "guide" lobes on the neck of the filter. After struggling to get the filter to seat, I took it out and compared to the old one. The construction is different and minimal that it is hardly noticeable, however since the filter will not seat, it leaks profusely.  Fortunately I found a previously purchased filter and discovered the difference. I would not, and will not buy these again.  So sad, they ruined a good thing.
