The design is perfectly fine: very lightweight, compact enough to fit into a modest size camera bag and it charges the NB-2L battery in about an hour give or take (charge time is mostly a function of the charger). It has flip out plugs (2-pin, non-polarized if that matters to you, and it may if you live in a real old building or outside the US) that fold back into the body - there is no cord, it plus directly into the wall socket. And thus, the only potential for design improvement. Most outlets are placed low to the ground, so to recharge your batteries, you must either stoop down or hook it up to an extension cord, but then it wont sit too well on a desktop. There is one other manufacturer, and the only one Ive found, that makes a CB2LT compatible charger that is a desktop charger - it comes w/ an A/C adapter and sits nicely on the desktop. Ill be nice and not mention where to get it but look around on the web, youll probably find it.
