Torn between whether or not to purchase a step down transformer and bring my Dyson vacuum, Kitchenaid Mixer and Cuisinart Food Processor. I've read varying personal experiences on other forums - some say these items work great as long as you have a large enough transformer (double the wattage), and others say anything with a motor (which all of these items have) will not work well. Anyone have personal experience with these specific items? Thank you!
