Product review (5 stars): Works well!
I have been using my waterdrop filter for about 2 weeks now.  I am happy to report it works very well.  The filter cartridge is a bit smaller than the Samsung filter it replaced.  There seems to be no issue because of that.  The filter installed the same as the original.  There has been NO leaking.  As for taste and smell, I live in Florida and the water is terrible.  Normally, there is a strong sulphur smell and taste.  The water tastes great when dispensed through the waterdrop filter.  Equal to the far more expensive Samsung filter.  I was skeptical at first because the price was so low, but pleasantly surprised to find I can pay much less per filter and still enjoy great tasting water.  I will definitely be a repeat customer.
