Product review (1 stars): A drop is all they can handle now...
In the past I gave these 4 stars. 1 being knocked off for how sloooooow they were.  Little did I know, the worst was yet to come.  I don't know if they changed something but they're now soooooo much slooooooooower.

At the 20 minute mark, and after having tried two different filters, I finally gave up when our gallon jug was "close enough" but not actually full.

I do like that this was usable on any pitcher or even water bottles with narrow openings.  Sadly that feature isn't enough.  I jist cannot recommend them anymore  as I now feel the name "drop" is a description  of how much water this filter can handle.
