Product review (5 stars): they were fine. No leaks
I had a little trouble clicking them into place (the prior PUR filters never had this problem). I suspect this is what's causing leaks, for some of the other reviewers. I had to use quite a bit of force to get them to click into place. Once I did, they were fine. No leaks. Still... it didn't instill confidence about their construction.

Update: After almost a years' use, I've used 2 of these filters, and have had no issues with taste (as some reviewers have complained about), so I'm upgrading my rating from 4 stars to 5 stars.
