This is such a good rabbit vibe you will find yourself using it all the time. And the good thing is, you will never need to replace the batteries. The vibe is totaly rechargeable and comes with it's own charging base so no need to ever have to replace any batteries. Keep it on charge next to your bed and use it again and again and again. It comes with all the usual rabbit vibe features including a silicone oscillating head, rotating shaft, metal beads rotating in Two directions and at variable speeds and a Four speed clit stimulator. And finaly, did I mention you don't need to keep buying batteries for it? oh I did! Good. Uses 4xAA batteries (not included)........... Joking, absolutely no batteries required what so ever...........ever.
