Yes, buy extra batteries and have a small screwdrive handy when the batteries need replacing. The screwdriver is required to access the batteries. Also, I have found that when using an ATC the temps tend to spike up quite quickly when opening the lid for more than a few minutes, such as when flipping over the meat. So 10 minutes before opening I turn the unit off: the temps drop, but I don't get the temp spike. Other than that, the PartyQ works great.
