Perfect size for my needs.  I use it for some xtra convenient storage (cell, cigs, gum,  etc.) and for a bit of occasional trash. Fits the hump great,  doesn't shift around, and is not obtrusive in size..  Leak-proof lining and easy removal for cleaning are definite pluses. I find no issues with rigidity as some reviewers have stated, perhaps they are not snapping in the supports.  My only gripe is that at $20 it's a little pricey.
