Worked well. I also normally use Apple Juice, but I was following PattioDaddios procedure, so I thought I would give it a shot. Not sure if I can say it turned out any different or tasted any different from using apple juice.
I have used a bunch of different digital thermometers over the years.....and it is by far the best. Not only can you see temp of meat and pit, but it's accurate and wireless distance can't be beat. I can sit in my basement and still get temps.
