The Panasonic tooth brush just mainly vibrates. There isn't any actual swivel or brushing motion.
For my travel kit, I usually just like to keep it simple (and cheap) and buy whatever is on sale at the drugstore. Travel toothbrushes tend to get icky much faster than toothbrushes at home so I find that I dispose of them or repurpose them, after a dip in bleach, for other household cleaning chores quite regularly. I usually prefer manual toothbrushes but I like using electric ones for whitening toothpaste.
I'm not familiar with the Sonicare line although I have heard good things about them. On Amazon there are some models going for under $20 which may be a good bet for travel?
