I love my Shock Therapy electrode kit, which I bought on Eden about a year ago. This introduced me to the lovely sensations of electricity.
Unfortunately, however, there isn't a very wide electro-stimulation selection here on EF, and most other sex toy sites (particularly tho ones that target the kink audience) are shady-looking and a hassle to deal with. Most people would rather not buy from these types of websites, which leaves us rather limited in accessibility to certain types of fetish play. =/
I keep wishing Eden would stock more quality e-stim toys, like the Neon Wand and it's accessories.
