A:Answer None came with mine, but I don't see the need for one. There are no protrusions to catch on anything or break off, and the unit itself is built quite solid. In my opinion, a carrying case would likely add size and make it less portable, and the whole idea of the product is to be an unobtrusive portable measurement device. If you break it while it's in your pocket you probably also did some damage to yourself or your clothes. You won't break it dropping it unless you do so from a tall building.
