Thank you for posting this question; I've been wondering the same thing. I have (and love) the Pure Wand and have been tempted by the Vr9 because they look like they would have a very similar effect, except for the vibration.
I'm glad Sammi and Rossie pointed out the "give" factor. I've never had an internal vibrator, so I didn't realize it would have more give. (My Ella has more give and I'm not as fond of it as I am of the Pure Wand.)
Did you end up getting the Vr9? If so, what did you think of it? There have been so few reviews on it that I've been hesitant to order one.
