Seconded. I haven't used anything but an adapter for my electronics in Europe for the last ten years and haven't fried a computer, tablet, cell phone, GPS, or anything else. Through several sources, I've heard that hair dryers aren't so reliably protected, but I don't use one of those normally unless the hotel/B&B provides it and then, it's only to dry clothes, not my hair.
