They are great with costumer service. When I bought my "open box" unit I wrote them a email after a few days when I noticed that my status went from processing to backordered.
Not 45 minutes after I wrote a email I had a call from them explaining what happened. It turns out the unit I bought was the last one and while doing their testing prior to shipping they found out it wasn't cooling. To me it's nice to know that they actually did check it.
They quickly offered to either leave me on back order and the next unit is mine or they could discount a brand new one and shipp that same day. I said charge me the difference and call it a day.
Great people over there
