Not Sure About this Technology
I wish that there were other reviews on here, so that I could see what others are experiencing.  Using this device, I don't get to a stable temp in 20 seconds as recommended, it just keeps going up long after that.  So I don't know how to gauge its measuring capabilities.  I've never seen the temperature go down as I held my thumb on it, stressed or not.  Not very impressed at this point and would not spend the money again.
