Nice add-on, but NOT a stand-alone product. (11 February 2008)
I got my Clip-It-Up base and top tier units today. They were lightweight, sturdy and easy to assemble.
Looking at the photo, it appears that the upper tier may have a stand of its own. Not true! (which is why I give this unit four stars instead of a full five) The base can be a stand-alone unit, but to use this upper tier you must attach it to the base unit.
The ring on this upper tier is the same size as the base unit ring, so like its big brother, it holds a lot. It is shorter, perfect for smaller items such as small packages of stickers, brads, eyelets, ribbon rolls, etc.
I didn't check to see if I'd be able to add another upper tier on top of this one, but I think it may be possible.
I considered making my own, like some of those I've seen on this and other sites. But I changed my mind and I'm glad I did. The ring is heavier than those lamp shade rings used in the homemade version. And if you take a look at the photos of the homemade style, you'll find that the rings tilt a bit when stuff is hanging on it. Not so with the actual Clip-It-Up. This piece of plastic and metal ring are surprisingly sturdy.
