This pill organizer is far superior to any others that I have used, which is a lot! The lids snap securely closed and then each daily container goes into the larger plastic holder, and that snaps shut. I have used this for travel many times without any problems. Would highly recommend this pill organizer for anyone that takes meds twice daily and gets them ready for the week. I just recently ordered a second container and now organize my meds for two weeks at a time!I use mine for vitamins. I have some I take in the morning and some right before bed so this is perfect. I love the rainbow colors to keep track of each day! It also comes labeled with tge day of the week. Its perfect if your going to be gone all day because you can just take the one day with you. I bought one for my daughter in law, my mom and my husband. They all love it too. Keeps us consistent and helps us remember whether we took our pills/vitamins that day!I bought 2. They seem to be sturdily made. I like the fact it's a double secure system and if you drop them, all the pills will not roll out. It has adequate space for the amount of pills I take and so far, I'm glad I made the purchase.I absolutely love these. I have used numerous different types and these are the best. Clear holding case for storage. Clearly marked days, easy to refill and they hold a large amount of pills. Definitely recommendit is compact yet holds a good bit. i like that it is colorful what i don't like is that the covers don't stay straight up to make it easier to get the pills in, but yet it is doable. i just do AM then PM so some meds that are twice a day i just open the bottle a 2nd time. for me i put the day i am on on top of the box after taking morning meds then after evening meds i put the day i completed with the day of the week upside down, then the next day is rinse and repeat so to speak. (it is also helping me keep track of what day of the week it is (and that for me is a bonus)I take a number of supplements/vitamins each morning and evening and this was the perfect size for travelling. It accommodated 6 pills on each side (and probably could have fit more). The labels were helpful and I had no issues with going through airport security or the cases popping open.had always used the cheap ones from the 1.25 store,mostly sooner than later they would break,so the last one I bought broke the same day I bought it..enough, is enough, had good reviews, so bought it, and so far I see a long life ahead..thnksThis med container is sturdy, easy to fill, and great for twice a day use.Grate for ppl with a lot of large pills . Also grate for travel
