When this duck arrived, I was impressed by the size. I was expecting something a little smaller. This was a pleasant surprise. It was ready to use right away. As soon as placed the duck in the tub, it started to calculate the temperature of the water. If the water is within the right range, the LED light turns green. If it is too hot, the LED turns red. If the water happens to be too cold, you will be met with a blue light. The packaging also has a chart that indicates the respective temperature ranges.
I have two children. One is 6-months old and the other is 3-years old. Parents always worry when it comes to dealing with babies. This duck helps to put your mind at ease when it comes to the bath water. The thing I like most about this duck is that it was simple to teach my three-year-old to read it. He has a bad habit of jumping into any bath that is run. Mine are usually way too hot. Now, I sit the duck in the tub and he knows not to jump in if the duck’s light is red. This is so simple a child can use it. I received a sample of this duck to test.
