I'm a quality geek and I like the plug ins because they last longer. The drawback with them is a lot of them are louder (not good if you have roommates, kids, thin walls, etc.) and it's nice to have a lot of outlets in your house if you like to stroke in different places.

www.sextoysforwomen.com is a nice place to surf . . . but you might want to order from someone closer to home.
