great system
I already had an RO system, so my lines were already run, however, this system wouldn't have given much trouble hooking up brand new. Tube colors are all clearly identified and the horizontally mounted membrane filter is a real plus. My old system (and many others I've researched) are much more difficult to get to the membrane.
