I bought this for a friend for their new baby, as this thermometer is simple and easy to use. We had two other thermometers that were more sophisticated and more expensive. However, these no longer work in giving accurate temperature. The duck thermometer that we own (same as that purchased) has lasted three years and is still going strong. Simple, effective and reliable.
Works but is very thin & flimsy, seems like it needs laminating, it feels like a piece of very thin card, not sure how long it will last once being put in water a few times
