Product review (5 stars): Does The Advertised Job
Works fine, no taste of anything foreign in the water.  No turbidity or any sign the filter is not working properly.
Just a warning, previous filters I have used have had grey "dust" from the filter media in the first few cups of water.  The first cup of this water came out black.  I would assume Waterdrop uses a different filter media.  Do not freak out if the initial color is not what you expect.
