The Wonder Vibe 4 is a semi-realistic vibrator designed for vaginal use. The very pronounced ridges stimulate the vaginal walls and the curved head seeks out the G-spot, although it requires some bending to actually get it at the right angle. While it is not the most girthy toy, it's filling enough to still get you going. Though size-wise it is more of a beginner's toy, the texture of the vibe makes it appropriate for slightly more experienced users.
