Product review (1 stars): Filter clogs up after less than 20gal to a mere trickle
We have bought the WSL-3 before and they were great, but the last batch was not worth a cent. Water output was slow from the beginning and within a month slowed down to about a 30sec just to fill a glass. We might have gotten about 20gal out of each of the three filters before I had to discard them. Not recommended. We just bought a different brand and what a difference it makes - the glass is full in 5sec. So it's not our waterline, looks more like they used cheaper material of a lesser quallity.
Water Sentinel - never again.
