I purchased almost two years ago; bought two: one for plumber to install in rental, and one for here.  with frostbitten toe and very cold weather I decided it was best use of time to finally install.  the long, very flexible stainless steel supply lines are fantastic since there is a shelf in the cabinet and miserable access.  Bless the person who decided on them.  the tree piece securing hardware needs to be made into one piece; with only one hand access I had to duck tape the ''U'' channel in place and then reach in with the tube and nut.  As BDI instructor in DFMA I can assure you they can easily be combined
