Well if things get a little crazy I don't want to be worrying about where these bunny ears are going, And I am sure after a couple of days you would just be sore from it. I'm sure some are softer than others but I just rather not mess with it. Soft smooth and round is fine for me!
I have both the Jopen Vr10 and Vr11--one has bunny ears, the other doesn't. The bunny ears never hurt, because they're soft, and they provide a different kind of stimulation because the bunny ears kind of flutter.
This is so much better than bunny ears . You don't have to worry about hurting your partner. Why bunny ears ? Whats so good about it.
I had a different vibrator with ears. I have no clue what rabbit you had, but they had more of a tickling/rubbing/vibra ting sensation that felt AMAZING, I like it way better than that sort of attachment, but that's just me!
