If I could give this a 0 I would. This product simply does not work. It failed to detect the thermometer in app. I did get it to show up in the app by adding it in my phone's Bluetooth settings. After adding it clicking on the device listed just checked/unchecked a checkbox. I tried pressing anything I could in the app to bring up the settings, but all that came up were instructions and an info page in Chinese. After restarting the app the checkbox was gone and clicking the device brought me to the settings page, which was confusing and unclear how to configure. I figured if the device worked properly I could get over the abysmal app experience. (which I half expected to be the case with a cheap thermometer). It did not. Shortly after initially connecting I got an error that it disconnected. It has a very short range (5ft) and I thought maybe I had walked too far away. The picture I took is with the "host" and probe all within a couple of feet of my phone. When it did intermittently connect throughout cooking it did not update the temperatures in the app. After finishing cooking, and taking the temp with my old thermometer, it did update the temperature! And I got a warning that the ambient temperature was too high, over 60c. Are you kidding me? The ambient temp can't be over 60c? What is the point of a wireless thermometer if you can't put it in an over, deep fryer, barbecue, etc.??? Save your money and buy a regular meat thermometer, or a wireless one from a well-reviewed reputable brand. This is a piece of junk.
