Query: Trusted & Reliable, Dummy Proof

I was very happy that I had purchased this thermometer when we had to check our son't temperature the first time. It takes the guesswork out of how far you need to place the sensor tip. I'm not saying it's perfect for everyone, but it gives you the confidence that you won't accidentally puncture your newborn in any way. It was one less thing for us to worry about and every little thing helps when you're frantic with a sick newborn. I recommend it.
