I have the GrillEye meat thermometer from Costco it came with 3 probes and was a really good price. I used it for about 15 smokes. The last 2 times I used it 1 probe would stop working proper during the smoke it would not read proper temp and sometimes jump up and down 50 degrees farenheit. Debating if I should return it and get a new one or just get my money back and buy a different brand. Anybody have one of these and do you have issues also or no issues at all.
