Product review (1 stars): Please pay attention to one star garbage reviews
If you came to one star reviews for advice, please pay attention to the "Do not buy this junk reviews" You will be sorry when it arrives after several weeks on a slow boat from China. Thinking you will outsmart the reviews like I did is just more aggravation. The temperature fluctuates in a five degree range continuously. If you wait long enough, every half hour or so
it will show the correct temperature. You can guess when it's correct or have another thermometer next to it to be sure..
