Customer Reviews

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.

Great iOS software design.

The software interface is excellent for the iOS. Hardware needs some tweaking as the monitor can easily slip off the key ring piece. I'm an original kickstarted and it has just worked perfectly since day one. Highly recommend it.
