This unit comes from a local estate that we are liquidating, it is more of an open box than used, it looks just as good as new with the manual and the the power cord, put the key that activates it. Unit is as good as new, the only reason it is been listed as preowned is because I could smell scent in the bottle, they could be tested too before packing, not sure about that. However, unit will be delivered in as good as new condition and working, you will not be disappointed. Will double box and ship for $20.00 anywhere in the continental USA.
