This is the 7-day pill box with a built-in timer that alerts you when it is time to take your medicine. Intuitive buttons and a large, easy-to-read digital display make it simple to set up to six alarms that beep loudly, ensuring you never forget a dose. Its 28 large color-coded compartments are divided into seven daily trays (four compartments per day) so you can presort prescriptions and tell at a glance what you need to take and when. The airtight lids seal securely, and the daily trays remove to take along in a purse or briefcase. Requires two AAA batteries. 4 1/2" L x 2 1/2" W x 2 1/2" D. (7 oz.)
