My students use portable CD players and a digital camera on a daily basis, thus I use a battery charger at work everyday. It is great, and it charges in 1 hour. The charger I just purchased for home (4 hour charge) is neat too. It even came with a car charger (handy for car camping and road trips). I only wish you didn't have to charge the batteries continuously. It seems as though they lose their charge if you don't use them immediately after charging. This causes me to keep batteries in the charger at most times, which seems wasteful. Less wasteful than disposable, but unnecessary nonetheless.
