I bought one a few years ago and although I don't use it daily, it sure is handy when I do!
We have a large, deep built in closet in our bathroom. I have those 3-drawer plastic units on one shelf with all kinds of supplies. So I labeled each drawer - bandages, oral care (meaning toothbrush heads, floss and toothpaste), shaving, etc.. Now, I can go right to what I need without opening 4 drawers to get the item.
