The Invisible Clock is an assistive device that works great for timed voiding programs, medication reminders, meeting timer, exercising, and literally hundreds of other activities when a flexible timer is needed. The unit has 12 daily alarms that can be set for specific times. This provides you with flexibility when a specific interval is not practical. Alternately, the unit allows you to choose a specific interval if that is more convenient. You can even choose both. The 12 alarms are automatically organized by the time of day, so it's easy to keep track of your programmed alarms and easy to check, erase, or set additional alarms. The Invisible Clock uses a vibration system (similar to that of a pager) that is private yet easy to feel. You can even adjust the vibration or beep low for a gentle and quiet reminder, or higher for a stronger alert. The single AAA battery is easy and inexpensive to change. The Invisible Clock is affordably priced, easy to program, and easy to use. Includes belt clip and battery. Comes with a one year warranty.
The Invisible Clock is a great alternative to a wrist watch and is the most "customizable" unit that we have found on the market - allowing up to 12 specific alarm times or up to a 999 hour auto reset countdown mode! The vibration is only 6 seconds versus about 20 seconds for the watches, but most children will still respond to this length of vibration. The unit must be worn next to the body to be felt (e.g., waist band)- which is a disadvantage for a number of young children. Also, children are more likely to lose a device clipped to the waist, than a watch worn on the wrist.
