Good quality product but closing is assured by the shape of the case layout which is calculated to put pressure on the spring type 2 1/2 lids, not easy to handle initially to store the scanner, more dimensions not used to store any cable inside. I would have liked an outside pocket for 1 cable and 4 AAA replacement batteries. That said the cramped side of the kit ensures perfect calibration of the scanner can no sloshing. good product to recommend.
