Query: Excellent, Tough and Portable Product

I ordered 4 large Medi-Chests a year and a half ago to compare them to the Medi-Planner II. As promised, I am publishing my results.These have met the test! They still snap shut tightly and no compartments have lost their tops due to stress fatigue from opening and closing them.Just as importantly, I can carry my plethora of cardiac, kidney, prostate and arthritis medications in one daily container when I go golfing, fishing, hunting or canoeing. If a compartment does just happen to open, it sure beats trying to put a week's worth of meds back in the right compartments!
