Best pill holder on the market!
I've bought 5 different keychain pill holders of different brands and sizes.  This is by far the best.  I use the small generic one to keep a $50 bill for emergencies, but it's not much good for anything else.  This holder, however, is just the right size, and the quality is exceptional.  Cielo pill holders are expensive, and I would never buy one at full price, but I will definitely be getting another as soon as they go on sale again.<br /><br />The threading is exceptionally smooth, and it's easy as can be to open and close.  The gaskets are of very high quality, and have stood up to dozens of openings and closings without a problem.  Also, I really like the double compartments, it allows me to carry both Imodium and Benedryl without getting them mixed up, and I can carry a good supply of each.  If I'm ever on a trip of 2-3 days, and I eat something that disagrees with me, I have enough Imodium to hold me over until I get home.  The compartments are also large enough to hold any kind of pill I've seen, although it won't hold many large vitamin-type pills.
