Product review (1 stars): Flood and fire hazard
I have worked on appliances for almost ten years.  In a bind I bought one of these machines.  I will admit it was used when I got it.  Within two days it flooded my apartment.  Upon opening the unit for repair I found that two hoses had simply popped off of their connections.  It seems that the element gets too hot within the unit and causes the plastic valves and connections to soften.  This makes the hose clamps insufficient to maintain proper pressure to hold their respective connections.  Again the element is hot without proper airflow to move the heat out of the casing.  I see this as a fire hazard.  Even if the unit vented into the space surrounding it, it would be better.  It may not "require venting", but it should.  I knew better than to buy a unit without having properly examining it.  Please don't follow in this fool's footsteps.  Buy something else.
