We are very satisfied with the design and quality of our new Kraus faucet.  The installation was easy using the installation manual, but I used braided stainless steel supply lines, instead of the ones provided by Kraus.  We love the design of KPF-1673 faucet with its flat and rounded neck design, which compliments the other stainless steel appliances in the kitchen.  This is the first single handle, pull-down type faucet we have owned.  It is not difficult to operate at all, but there is short learning curve, so you don't spray water outside the perimeter of the sink.  After you use it once or twice you will have mastered it.  All-in-all it is very high end and professional product that we a looking forward to many years of trouble free service,
