"Great help when frying"
I've only used this when frying fish/fries/hushpuppies, and it was a great help. I haven't tested the product for accuracy, but it worked perfectly for helping me to regulate the temperature of the oil. Last time I cooked, we were cooking for several people and hand two pots of oil and only one of these... the pot without the thermometer was much more of a hassle trying to regulate the oil temperate and resulted in some burned food.
Highly recommend this for frying!
One note, for best functionality, attach to the pot with the integrated clip and just leave on the pot. At first we tried to share between the two pots, but it takes approx 30 seconds for the reading to level off... so not very practical for more than one pot. At this great price, just buy two!
