NEW Express Water 5 Stage Reverse Osmosis System Plus 7 Extra Water

NEW, Factory Sealed, Never Opened, Express Water 5 Stage Reverse Osmosis System Plus 7 Extra Water Filters.  Purchased a few years ago for $139.99, but after testing water again, did not end up needing a reverse osmosis system, so it was never used.  It is listed as Model AZ+7, 5 Stage Home Drinking Reverse Osmosis System Plus 7 Extra Express Water Filters.  It weighs approximately 31 pounds, so shipping is expensive.  I've included pictures of the original packing slip.  It is the equivalent of the current model being sold on Ebay for $169.99.
