I recently got a Snake Charmer. The quality is, of course, up to TB standards. The double zipper pulls and the pull tab on either side make it very easy to unsip part of the SC to get the item you are looking for and the two compartments are great - computer cords on one side, cell phone stuff on another.
There is one huge downside for me though. There is no place to put it in a TB bag. If you use packing cubes for most of your stuff then this odd sized and shaped "cube" doesn't fit. I expect to use a regular packing cube for my cables when packing a TB bag
