I purchased the 24qt unit. I was looking for something to do hot holds on brisket. The fact that this says it can do 150F was perfect. Unfortunately after receiving the unit and cleaning it I tested the unit with my thermometer. When I had the knob set to 150F the roaster actually spiked then settled at 200F. I then checked with multiple thermometers all had the roaster +50F of where it was supposed to be. I ended up finding the sweet spot of where my unit actually sits at 150 and I marked it with a marker.
