I myself never own a CyberQ nor DigiQ.
I just read a post from Q-talk and find BBQ Guru adjusts maximum blow manually by fan vent. A fan has fixed capacity of 10 CFM, if you blow 5 CFM to pit, you waste the other 5 CFM.
In my GOLDEN-DOG, sooner new name QMaster-Junior, you can adjust maximum blow by programming a parameter of Hdc, say 10%, 11%, 50%,61%. The fan will run slower accordingly.
If you use a battery in outdoor other than AC/DC adapter, this feature saves a lot of battery.
But Golden-DOG is so weaker than Guru in the market.
I must need professionals in marketing and sales
