Product review (5 stars): Seems to work.
Seems to work.  But made noise when first used that has since gone away.  The hole inlet is a lot smaller than the Samsung one.  But this is made in Korea so expect close ties to be a positive but not sure the noise had to do with the smaller hole.  Also does not have "Open" imprinted on the twist handle.
Do not detect any difference in water quality with the original Samsung.  Uses some kind of fiber am wary that may have BPA or phatalates in it.  Not sure.  Has higher gallon capacity than the Samsung.

UPDATE:  There is a new version and it seems to work better than the older version. Still makes noise when first starts but then goes away after a couple of days.  The hole in it is the same size as the original Samsung.  They even emboss "Open" on the handle now.  Like this "improved" version and giving it 5 stars instead of 4 stars.
