I purchased two of these for a double vanity in our master bath. While they look great, I have had a continuing problem with the flow of water. More so on the hot side than cold. I have replaced the internal valves twice as well as cleared out the lines but water flow rapidly deteriorates after making the change. Perhaps part of the problem results from not having a defused. That being said, tthe device staff has been most responsive in terms of providing replacement parts at no cost in an effort to remedy the problem but in the end the faucets do not perform to the level they should.
