Product review (4 stars): Easy install, over all.
I bought this kit in order to expand the capabilities of my single tap system to a dual tap.  I thought the extra regulator would come in handy if I had two brews with differing pressure requirements.  However, the high pressure tube that goes from the gas bottle to the regulator is a reverse thread.  You can't just go to the hardware store and rig up a Tee for this.  The fittings required to do this may exist, but I haven't found them yet.  If you are expanding a single tap to a dual tap, just piece it together.  You'll spend less.  The quality of the components is at least as good as the original equipment in my kegerator (a Danby unit).  My only complaint beyond the multi-regulator issue is that the kit contains no trim rings for the tubes that have to enter through the back of the cooler.  Installation was easy, and took me only an hour or so.  The dual tap tower fit exactly into the location of the original.  As long as you don't look in back at the penetration for the gas tubes, this system looks like it was built as a 2 tap unit.
