Product review (1 stars): Too Slow - Going back to OEM
I don't like the flow of the OEM filter to begin with, but this brand is way worse.  It was so bad I did a flow test.

OEM (LG) = 4 cups in 37 seconds.
Sentinel = 4 cups in 52 seconds.

Takes to long to wait for a glass of water.  Going back to OEM filters.
