Line length 92cm. This bedwetting alarm helps children develop nighttime bladder control through consistent training. The device features a highly sensitive sensor that detects the first drop of urine and immediately activates an alert to help wake the child. Suitable for children and adults who need nighttime bathroom assistance. Offers three alert modes: sound, vibration, and flashing light, to effectively notify the user and allow caregivers to respond promptly. Adjustable elastic arm strap ensures a comfortable and secure fit for both children and seniors. The armband is easy to put on and remove, and can be cleaned if needed. The sensor clip is detachable and can be wiped clean after use. Note: The main unit is not waterproof—only the sensor clip is water-resistant. 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, and turn on the device. Caregivers can track progress using the included progress chart with stickers, set goals, and provide rewards to encourage positive behavior and support long-term habit development.
