Hi,
I love my organizer. I got it at CVS.. don't know if you have those by you but it is round and holds one week of meds. The top comes off so you can easily add meds for the entire week. Then with the lid on, there is a button in the middle that when depressed, pops up. So basically you turn the dial to the day, press the button, the top pops open and then voila!
It also has a non skid base which I didn't think would be useful, but it stays put when placed on top of my coffee maker. It was all of $3.
