ToyTorture, a well established reviewer in Europe has posted a review on our highly popular E-Stm
ElectroEgg. You can find his review at
https://www.toytorture.com/e-stim-systems-electroegg/ although I don't agree that a sphincter could hold 12 kgs, the braking strain of the connection cables (and 12Kgs is around 26lbs!!!), and we don't recommend you take the ElectroEgg apart for cleaning.
You can track down the ElectroEggs on our UK/EU store
here, and our US/Worldwide store
here.
