Works well but don't expect miracles


I have had my device for a couple of years and it gives accurate temperatures. That is because I use a 4" phone jack extension that accommodates both speakers and mic (it needs all channels) to move the sensor away from my phone. If you don't do that it will read high! Be realistic. The sensor gives the temperature of what it is near. That means if you expect to use it with your phone in your pocket, you will be disappointed.

It works


It seems to be simple in concept and design. It shouldn't need a manual, but FAQ or tips might help some. I initially thought mine was inoperative on receipt. It was stuck at 25°C or its Fahrenheit equivalent either plugged into an extension cable or directly to the headset jack. Before I sent it back, I tried it on another iPad and it worked... Mine was set to monaural audio output, switching to stereo solved the problem.

Cute idea, not much use, no support


It's a cute idea but seriously flawed in at least 2 ways: (1) Inaccuracy because of heat from device - need a cable to move sensor away. (2) The sensor itself can fall off its holder and is easily lost.
But worst of all is the atrocious customer support. No response to questions, not even acknowledgement that a question was asked. I wouldn't recommend this product.
