The MemRabel is a memory aid designed for people who have Alzheimer's and dementia or anyone with a memory problem. A carer or loved one sets up the unit with four audio reminders that can be set for either day or weekly playback. The messages can be up to twelve seconds long which is just enough time to remind someone to have lunch or take their pills. The screen is large and clear and displays the time in twelve hour format. It has a graphic of the sun or moon so the user can tell whether it is day or night. This is a great product performing an essential task clearly and easily.
