Contrary to other reviewers, the charger neither switched on my Creative Zen whilst charging, nor did I need to switch on the Zen in order for charging to begin. I simply plugged it in (and it works fine in Europe with a suitable plug adapter) and charging began. The unit seems robust and well made. There is a red LED light to indicate power supply, but nothing that will keep you awake at night, unlike one particular competitor product. And charging seemed to take about the same time as USB charging, again contrary to another reviewer. From my experience of this charger I don't think you could do better at this price.
