I bought this electrode to compliment the Flange that I already own. I am a bit of a texture queen and absolutely love the ripples along the side of the Deviant. Just inserting it has me on the verge of a very powerful orgasm. When I switched on my Series 1 power box that did it and sent me over the edge. The Deviant is a very capable, well machines piece of sextech that will have your writhing in lustful ecstasy. Its very large surface area makes it a very eficient electrode and the sensations that this delivery are mind blowing. I have the medium and have found this to be the perfect size for vaginal e-stim fun for me.
