I don't get what you mean, Surf M. Yes, the box clicks shut, but it doesn't keep it shut. Also, it doesn't click open, which would help to let you know it wasn't closed. Rather, a millimeter or two slide in the lid actually opens the box and allows finely ground contents to spill. I don't like this 'improvement' and don't understand how others can. It's just another feature that detracts from the basic simplicity and function of the unit. The battery o-ring - great, I often have a hard time pulling out my tight-fitting battery from my older unit. The lid-lifter 'latch' - not a good idea.
