Vibration: A more effective alarm clock
An aid to waking up that makes a big difference!
Place it directly under the mattress.
You can also place it under the pillow, but it will be most effective under the mattress.
The vibrator can be used alone without an alarm (does not wake up the whole family) or in combination with the alarm for a more effective wake-up. A major advantage
One of the great advantages of adding the vibrator is that it allows the alarm volume to be kept to a minimum in most cases. This is very appreciated by other family members.
Adding vibration is a major asset for waking up deep sleepers. The vibrator is included and is an integral part of the Dry4ever system.
