This is an incredible little control box packed full of great features. I found it be very powerful and with very easy to use controls. The five different operating modes are a lot of fun and it never fails to give me some amazing hands free orgasms. I have used it with several different bi-polar electrodes both vaginally and also anally and it rocks. The pads in this kit are very, very sticky so watch out if you are using it on a hairy area. They can also be re-used. All in all this is an amazing kit that I would highly recommend but get yourself some bi-polar insertable electrodes to really explore its capabilities.
