Line length 92cm. This bedwetting alarm helps children develop the habit of waking up after urination through subconscious training. The alarm has no side effects, and the highly sensitive sensor detects the first drop of urine and immediately alerts the child. Suitable for children and seniors. Features three alert modes: sound, vibration, and flashing light, to effectively wake the child and allow timely assistance from caregivers. Adjustable elastic arm strap ensures a comfortable fit for children and elderly users. Easy to put on and remove. The armband is removable for cleaning, and the sensor clip can be wiped clean after contact with urine. Note: The device is not waterproof, except for the sensor clip. Simple to use: Attach the sensor to the underwear in the area most likely to come into contact with urine. Remove the battery insulating strip, turn on the switch, and the system is ready. Caregivers can track the child's progress using the included progress chart with stickers, set achievable goals, and provide rewards to encourage consistent toilet training and build positive habits.
