Product review (1 stars): Manufacturer did not stand behind produce
I bought this unit and immediately went out to get a copper core all-clad dutch oven to use with it.  The very first thing I tried to make (braise) burned at 160* setting and nearly ruined my pan.  I tested with the pan provided by manufacterer and found that the 110* setting is really 160* with each setting accordingly higher than marked.  When calling the manufacturer, they claimed the unit is not broken,and that the settings are subject to variances.  All advertising expressly states precise temperature control.  The manufacturer would not replace as they said we would have the same problem we described.  The vendor did however accept our return.
