So I just picked up the Wahl 2-Speed. As much as my wife and I have LOVED the Hitachi Magic Wand, had to find something that was quieter. Kids are getting older and don't want to explain why dad was operating lawn equipment (or something that at least sounds like lawn equipment) in the bedroom at night with the door locked

After reading the reviews and posts, figured the Wahl was a good fit since my wife needs a lot of power to get off. One thing I liked about the Hitachi was that the large head made it easier for me to use on her, which is important b/c I don't get a lot of feedback when using toys on her. Just the old "everything you do feels great" and obvious orgasm feedback. So if you were going to have your partner use the Wahl on you, which attachment would you want them to use? Any other tips you'd like to provide is also appreciated. Thanks.
