It worked once. For the second time, he would not go into "water" mode and it displayed the temperature of the room even though it was immersed in water at 38 ° C. Then he started "raving" by displaying 42 ° C in the room.
Still, I'm an engineer and I tightened the battery cover. For mine, the water is returned by the upper part below the green rubber band.
I deeply regret my purchase because of the price. Now a 4 euro thermometer Beast fulfills its role.
Really shame for the company that makes these thermometers and offers us products of poor quality.
To avoid absolutely !!

Update: I just open it. The quality is one kind of Chinese "no name" After removing the green band, I saw the space through which water seeped. They put some silicone, but not enough to make it waterproof. I have also observed an off wire (one that closes the circuit in contact with water). I have cleaned and dried, I glued the wire and now it seems to work well. I must be sealed after assembly.
Finally, counsel for new buyers: before plunging into the water, remove the green strip and turn well to do well silicone sealing.
