By Ian (Fremantle) — 26 September 2022 Not inexpensive but a brilliant device to control the cooking/smoking temp over long periods of time in my Kamado Classic. It keeps the temperature amazingly stable for the duration of a cook without having to fiddle with air inlets/outlets. Very, very effective. The probes (one for pit temp and three for the product being cooked) are very helpful and interface with phone is very helpful.
