I love my Party Q and its battery operation over my Digi Q with its power cord. I recommend getting some rechargeables, they last me through entire butt and brisket cooks and I just swap them before a cook. That being said, the more airtight the smoker, the better the Q does. I use mine on my two Weber kettles but with the One Touch ash catcher they leak a lot of air in. I put strip magnets over the ash carcher intakes and it helps the Q a lot on the kettles.
