I don't use a controller often, just for overnight cooks, especially if it snows. And as already mentioned, if i spend $200 on a chunk of meat I will sleep fine with the Fireboard handling the temps. I'm over 60 so i'll be up at least once in the middle of the night to hit the bathroom and it is nice being able to just take a peek at the phone and see how my cook is going and not have to even think about going outside. No issues with connectivity for me but i don't think i have ever tried the Pulse with a foil wrap, I use butcher paper for wrapping. Maybe I'll give that a try just to see how it works.
