Well, surely works perfectly. However, the bright blue light is a bit pushy. Measured with a multimeter I charge voltage of 3V. This means you can let the controller safely lie in the charging cradle. Overcharging is not possible at 3V, the attached 3V have after the batteries are fully rather as a maintenance character. This means that the batteries are kept permanently full. The shape and design however, could be better. Everything pretty kipplig and wobbly. Who does not disturb however, it should have no concerns.
