I've always wanted a thermometer like this, and I have a 2-year-old child who rarely stays more than 30 seconds while I have every thermometer. They will take FOREVER to take his temperature (30+ seconds!) and it may not be accurate, so he never really worked with me when he took his temperature. But this thermometer is very convenient to use, before my child would try to absorb the temperature will scream and escape, but now he really like it and can do it himself! If have 2 people in charge do not transfer bacteria when they are ill. This is a good project for children and adults with medical problems! Very much like it!! 30AQDXXO (30% coupon) $16 only! free shipping w/ prime or order over $25.
