I have REALLY enjoyed the Wild G. Its shaft is slightly curved which hits the G-spot better, instead of actual beads it uses something like ball bearings than cannot break off and feel much stronger, the shaft seems to curve slightly forward which really helps my stimulate my clit and the surrounding pubic bone area more and the bullet for the clit is really powerful!
linkHowever, I usually use it without the shaft rotation as I find that a bit..weird sometimes.
I would not recommend the Rabbit Habbit as it is very poorly made and does not seem to perform well.
