Lexington holds most temps. above 300. I wish I could find one that had 25 deg increments variable speed would be nice. 250 runs 195-238 so most of my smokes are based for 225ish cook Put 8lb pork butt in at 6:30 pm cent. time now it's 9:30 41 deg outside will probe and spritz about 6:30am and let ya know how it went!
