I got this primarily to make candy with. I wanted to know the accuracy, so I did the technique of submersing the probes into ice water and boiling water. Both probes read within 1 degree of each other and each took about 4 seconds to stabilize the reading. So far so good. I do note that it takes longer when testing non liquid items, but still seems to get a reading in about 6 or 7 seconds. I do note that while the display orients itself automatically, that this is easier to use right-handed than left. So far, with a couple months usage with several hours of actual temperature reading time, the battery meter hasn't budged suggesting that it won't need to be charged often.
