I was getting stressed guessing if the bath was too hot or cold, but this little duck just floats and gives a clear digital readout. It's nice that I can also set it in the nursery to check the room temp before naps. Works perfectly and feels sturdy so far.
Finally, a thermometer that actually shows both bath and room temp on one screen – no more guessing if the nursery is too warm. I've been using the floating sensor for a week now and it feels reassuringly accurate, even with a wriggly baby. Definitely takes the worry out of bath time.
