Even with the proper transformer, I have damaged 110v electronics. My computerized sewing machine had to have a complete expensive overhaul due to damage from running it on a transformer. A friend brought her kitchenaid mixer over and it ran fine for about a year, then just died! But I also ran a microwave and many other things for 7 years on a transformer and then took them back to the US and they ran fine for many years after that. So it's up to you if you want to chance it. In the future, as you purchase an appliance, look for a "dual voltage" type that you can just turn a switch and put a plug adaptor on to make work either 110 or 220. You can buy 220 kitchenaid mixers over here - i've seen them at Selfridges. And as in the US, they aren't cheap! But to have that power, sure makes it nice! Good luck and happy cooking!!
