For: Good grip, instant start, soft button, discreet and aesthetic standard AA battery and cheap. Against: Blister difficult to open and polluting, strong smell of plastic unpacking, battery not included (unlike the mention on the photo presentation "1 x AA Battery Included") lid smooth and awkward to handle housing, no support Wall, no notch for hooking (micro plastic support provided to ask, quickly lost). A test over time. Edit 1 December 2013: the unit is already down. Edit 2: following complaint, replace the defective item 24H and prepaid return label provided, though!
