I use it and like it quite a bit. I had tried a couple of other snippet managers, including Snippets, before settling on CodeBox.
You can set up your snippets in libraries if you like, organize them in smart groups, tag and annotate them, etc. You can also use TextMate themes if you wish.
I don’t know if it’s as “robust” as Snippets, but it’s more than enough for my needs. Easy to use, intuitive, and very reasonably priced, IMO.
