No, Rex won't be your friend and listen to you whispering sweet-nothings, but it will help you take your medicine correctly, every time. The Rex kit includes three bottles and a recording device for $55. This device is primarily targeted for the elderly or visually impaired. With a push of a button the bottle will play back the recorded dosage instructions. There are even participating pharmacies that have a computer to convert the label information into a recorded message on the Rex bottle.
