my first three cooks I tended all the time and was constantly checking temps and fighting it.....then got the Maverick wireless thermometer so I could sit inside and monitor meat and grill both...set alarms...timers...etc. Thought I would get a guru too later...now I am not sure as the Meadow Creek PR42 maintains temps pretty damn good....and being able to see the slight up and down fluctuations I am a much less stressed smoker/cook now with it than before.
I like being able to see what it is doing without lifting lid or relying on built in mechanical temp gauge.
where I could see it useful is for a long overnight hog....but only after I had used it and tested it enough to trust it completely. :)
