I wanted to see how the Party Q would do on the UDS. Lisa Jo from BBQ Guru had told me that the Party Q did not perform well on the UDS in their test...WRONG it works incredibly well. I suppose they wanted me to upgrade which i might do someday but the PQ does do great so i won't anytime soon. One thing about the Party Q is that it doesn't have the technology to sense when you're opening the lid to check on the food...but i'll share a trick i learned to bypass this short fall. Say you're doing ribs and after 3 hours you need to foil the food then what you want to do is .. 1) flip the switch off 2) un plug the probe wire After foiling do the reverse 1)flip the switch on and the Party Q will realize there is no probe plugged in 2) plug back in the probe (By unplugging the probe and plugging it back in it will erase the memory from the cook and won't try to over correct when you turn it back on) It'll very quickly settle back in at your target temp and stay right there dead on.
