Query: Very unreliable and inconsistant readings

This thermometer is about as good as not having one at all. On one reading it will say 102.7 (which nearly stops your heart) and the next reading (within seconds of the last) will say 95.3 - and the readings continue on like that. Each consecutive reading will have several degrees difference, so you have no idea what the true temperature is.
