I have now had this pill organizer for almost three years (UPDATE: ALMOST FOUR YEARS!!), and it is the best I've ever used. That's an accomplishment for this little organizer because I started taking daily meds over 10 years ago. In that time, I have researched and considered dozens of pill organizers and tried many. Durable: I TRAVEL FREQUENTLY, moving between cities for 1+ overnights at least once a week, sometimes four times a week. It sits in my laundry basket, the catch-all for all kinds of items including heavy backpacks, so the organizer gets squashed quite a lot by various amounts of pressure. As I said, I've used this for almost three years now and it's still functioning optimally. Big slots: These squares are the only ones I've found that are BIG enough to actually hold my medication. I currently have ten small-ish pills in one box and it's not even a third full. The other box is about halfway full with twelve pills, most of which are large supplement pills like vit B, vit C, multivitamin, and Omega-3. Unheard of in all my research. That means that this dispenser is quite large. It won't fit in a purse but fits easily in a backpack. The width and depth are smaller than my laptop, but the height is thicker than a laptop. The size of the squares is unheard of in my research and vital for my use. All the others are puny and fit like five large pills. People, what about us with chronic illnesses??? I know there's a market for this but no one has capitalized on it yet besides this super great dispenser. Secure: I was concerned that my child would get into this box to get the pills out but he's never touched it. 1-the organizer by itself looks boring. I like that because it reduces his interest. 2-the organizer is designed like a flat box with a lid and two latches on the side closest to me, designed kind of like a very squashed treasure chest with one of those latches hanging vertically for a padlock (couldn't think of another metaphor). The two latches don't have a padlock but they take both coordination and strength that a young child (probably) wouldn't be able to operate. Each latch requires good thumb strength to pull it open. A child trying to do both latches at the same time - it would be quite difficult for the child, certainly way more difficult than any other organizer I found where all the child has to do is pop a little lid open using a fist around the container and one finger. 3 - if my child wanted to open the slats on the top, he might be able to. I haven't opened the container in close view of him, and the little handle blends in due to being clear plastic, so that hasn't been a problem for us but might be for someone else. Still, this box was the most childproof with this much pill space that I could find. Filling & Dispensing: this organizer actually opens two ways. To FILL the container, I pop open the latches. The top, the blue side, of the organizer lifts up and away from me. Now the organizer is laying on the ground like the two sides of a book with the lid away from me and white boxes open closest to me. The blue side is shaped so that the white side is tilted a bit towards me while the lid is open, making it easier to see what teeny pills I've put in that sometimes hide from view. The organizer comes with LABELS at the top for days of the week. I'm on a different filling schedule, so I put sticker labels on top of the days of the week so it now says my day. I use two rows for one week and two rows for the second week so I'm only refilling every two weeks, which I like. Aint nobody got time fo dat filling up a pill box for a half hour every week vs 45 minutes every 2 weeks. Because of the design for dispensing, using it my way is very easy. Here's how it functions for DISPENSING. Each column has a single clear plastic slat. At the end furthest away from you, there's a little handle. When you are getting pills, you hold the little handle, slide the slat towards you, and it slides out close in front of you. It sort of clicks into place when you get to the end of one box, so it naturally prevents you from accidentally sliding it a centimeter too far and pills dumping out. The slats are surprisingly durable. As I said, I've had this for nearly three years. I try to be careful about bending them, but many, many times I've accidentally pushed on the slat while it was stuck out. It's so sturdy with just enough flexibility that none have ever broken even with various amounts of pressure against them. The single slightly negative part of the whole thing is that I have to TILT the container fully upside down and jostle it a bit to get all the pills because for some reason if I only tilt it 45 degrees from the ground, some of the pills stay in. I am still incredibly impressed even after almost three years. I have never thought to myself about finding something else because I'm so satisfied with this one. I highly recommend it.
