I used this unit for just 2 weeks. The remote unit was less than 40 feet away but even at that short distance I noticed that the remote unit was not showing the current temperatures. At least 3 times I noticed that the remote unit was off by 50 degrees. The worse part is that the food probe went bad after 2 weeks. I only used this unit with long and slow cooks with temperatures no more than 250 degrees. After only 2 weeks the food probe is registering 10 degrees over what the actual temperatures is. I'm not impressed.
