Shipment arrived in good condition and quicker then expected. Set up was very easy as all parts for installation were included as advertised. Printed instructions were complete and the video's on the web site were also good for additional information. I did a lot of checking of other products and talked with the local aquarium shop regarding RO/DI units and this is far and away the better product. The "PLUS" unit is worth the extra few dollars for what is included in the package.
