Malem™ bedwetting alarm with 8 random sounds (MO3(8) with flat plate sensor

This body-worn alarm by Malem is the lightest and smallest bedwetting alarm available. It weighs just 24g including batteries and measures 49 x 39 x 18mm. 

This alarm is comfortably worn on the nightwear close to the shoulder. After being woken up over several nights, the child will either wake up before they do a wee or will learn to sleep through the night without wetting the bed. 

The Malem MO3(8) features 8 different alarm tones that activate randomly. This may benefit your child as they are less likely to become accustomed to a single alarm tone over time.

The alarm sounds continuously until the sensor is removed, allowing sufficient time to effectively respond to the alarm. A flashing glow is emitted when the alarm is sounding.

Please note that the sensors are replaceable items. They do wear out and are not covered by the guarantee.
