I bought the BBQ Guru DigiQ DX3 without too much research. It does exactly what it says on the box and controls the temperature of my Monolith Kamado perfectly. I set it for a 110C slow cook and it maintained the temperature perfectly over a 10 hour cook. My regret was not checking to see if this was Bluetooth or Wifi enabled which it isn't, so I relied on my Meater type probe to give me the information I wanted from remote. In reality this does what I want, so to spend the extra £200 to have the wifi etc was probably not necessary. I am really pleased that I bought this piece of kit.
