I purchased 2 to replace drippy faucets in the master bath.  The pieces are heavy and made well. I installed the first one and immediately noticed the lack of water flow.  Double checked my valves to ensure they were completely open and they were.  I figured there’s likely a reducer so I took it apart to find that the reduction is built in and not removable.  I timed the flow rates between the two faucets, running them one at a time and this one puts out 60% less water than the drippy one I was replacing!  I have a similar faucet but different brand in another bathroom and the flow is what I’d expect.  Would have been  5 stars for vanity and ease of  install, 2 for functionality.  Yes water comes out, not nearly enough volume.
