I have a couple of the Witz boxes to hold some of my stuff. They aren't as strong as Pelican or Otterbox, but they're good enough without being too overkill. I modified the latches on mine to make it harder to accidentally open. All you need is a lighter and a sharp knife. Heat up the latch until it's pliable and bend it flat, then shave off a bit on the backside to allow it to latch more securly. Where before I would sometimes find it unlatched in my bag, since I've done that I've never had a problem with it opening accidentally.

BTW, I think that Lillipod is just a Witz case with a headphone jack. Has the exact same latch, and looks identical.
