I bought one this model pill container three years ago. At one point I was taking 13 pills per day (a few quite large) -- some in the morning and some in the evening. They all fit in just fine, although I had to adjust the arrangement of a few so the lid would close-- no problem. I've never had any lid pop open by itself. I have taken some compartments out to carry in a pocket when I knew I'd be away from home for a day. The only problem I've had with this Ezy Dose 7 Day Travel Pill Container is that the printed markings began wearing off after about 30 months of continuous use. During the past six months, I took to re-marking the lids with a fine-line magic marker and then placing a small piece of Scotch Tape over that. That was OK, but it looked pretty funky. I finally decided that since this was such a great product, I would buy another of the exact same product. The new one arrived today... and I promptly painted TWO coats of clear nail polish over the pristine lettering. I figure that I'm good to go with this pill container for at least the next FIVE years! I will be keeping a sharp eye out for any sign of the lettering being degraded, and will promptly apply a few more coats of clear nail polish if that should happen. ------------------- BY THE WAY.... I absolutely NEVER forget to take my morning or evening pills. Whenever I'm more than 30 minutes late taking my pills, my good friend comes right over and reminds me----and WITHOUT FAIL keeps on reminding me until I go take them! How can this be? It's very simple: I feed my beautiful Yellow Labrador Retriever twice a day... at the SAME time I take my pills. If I forget do do either one, just guess who starts sitting right alongside me nuzzling my elbow and giving me the sad looking eye? She doesn't want to miss her twice daily meal. Whenever I take my pills, her tail starts wagging. I highly recommend both this pill container AND a Labrador Retriever... -------------- Edit: Over a year later now... and the clear nail polish is still doing it's job of protecting the lettering. Alas, I must report that my dear old Labrador Retriever passed away and is no longer reminding me to take my pills. I have no plans to get another dog, but I did figure out another way to remind myself to take my pills. I got an old clothes dryer buzzer, attached it with some spade terminals to an AC plug, which I then plugged into a Woods 50007 Indoor 24-Hour Digital Timer, Daily Settings, 2-Pack digital timer. This timer can be programmed to go off twice a day for a minimum of one minute. I can hear that buzzer all over the house... and the minute long buzzing is just barely annoying enough to not ignore.
