They thought of everything to keep a person organized with pills and vitamins. It is a small chore to put in all the pills for one month, but well worth the time. No more wondering if a pill was taken and no need to search for the vitamin or pill bottles every day. I have taken the individual "day" containers with me on vacation, which is a real convenience. I do have trouble opening the lids and sometimes use a utensil to push up the tab instead of my finger. But that is good, as the pills stay secure with the lids. By flipping over the daily pill box to the opposite color, you also know the date...an added feature for those who are retired LOL. I have found that the larger sized vitamins fit well into the compartments...you can put in at least 4 extra large capsules into the daily compartment areas. The daily compartment areas are labeled for morning, noon, evening, and night. I fit 8 pills and vitamins into my evening section.
