The (hitachi) Magic Wand Rechargable honestly changed my life, if you’re on a budget I’d try the Tingletip Electric Toothbrush Attachment, or else I’ve heard the Doxy wands are even more powerful than the Hitachi
Something to keep in mind is that very pinpoint vibrations can sometimes feel more intense than a large powerful wand head, if you’re keen on a wand then a good attachment can make it feel even better.
