The ThermoPro TP-25 is a four-channel, Bluetooth-connected wireless food thermometer that is controlled via a free, downloadable smart phone app. It comes with four color-coded temperature probes, a USB cable to recharge the internal battery, and two grill clips.
The instruction sheet is pretty sparse, but the interface is intuitive enough that most users will be able to navigate around the app easily. You can also use the transmitter by itself if you don't need the features provided by the app. And you can turn off the Bluetooth transmitter to save battery power.
The transmitter has an on/off switch on the back that doubles as the Fahrenheit/Celsius switch. There is a backlight button on the front of the unit that lights the display for ten seconds. The display also shows remaining battery life and the Bluetooth status, as well as the °F/°C units in use.
For each channel, you can set an alarm triggered by rising temperature or by a timer. You can annotate the timers with directions like "Flip meat" or the text of your choice. If the app crashes, the temperature alarms are retained, but the timers cancel, losing your place in the time realm. Unfortunately, crashing can be a frequent occurrence. Each of the four channels has its own graph of temp vs. time. The labels on the graphs are in the tiniest font, making them very difficult to read without a magnifier. Temperature accuracy on this unit is good.
Contact info for the manufacturer is found in the accompanying documentation. The warranty can be extended to three years from one by registering the product online.
The overall quality is good, but the instability of the app, especially when the timers are in use, is troubling. Hopefully they'll get that straightened out. This is a pretty basic unit at a pretty reasonable price.
