Tingling that goes deeper than any vibration - that’s the mystim Opus E Donut.Why is the mystim Opus E Donut electro masturbator so good?Electrostimulation works differently from vibration because it doesn’t make the surface vibrate, it directly targets the muscles and nerve endings - the sensation is typically tingling, pulsing and can be adjusted far more subtly. The Opus E Donut provides a soft, lifelike TPE sleeve with steel contacts that conduct the impulses, while the rigid ABS case gives you a stable grip. The inner surface is textured, so it’s a fully functional masturbator even on its own, without current - the electrical part only comes into play when you connect it to a mystim unit. The 2 cm, highly flexible inner diameter adapts to a wide range of sizes. It’s ideal for those who have moved beyond traditional toys and would like to try electro-sex under controlled conditions.Why customers like the mystim Opus E Donut electro masturbatorElectrostimulation - controlled impulses when connected to a mystim unitCan be used without current - a fully fledged masturbator in its own rightSoft, lifelike TPE sleeve - pleasant to the touch, realistic feelRigid outer case - secure grip, doesn’t collapse during useTextured inner surface - stimulates the entire length of the penisFlexible interior - adapts to a broad size rangeRemovable inner sleeve - can be cleaned thoroughlyGerman design - mystim is one of the best-known electro-sex brandsContents of the package1 mystim Opus E Donut electro masturbator (natural inner sleeve, black case)1 pair of adaptor cablesProduct featuresMaterial: TPE (inner), ABS (case), steel (contacts) - phthalate-free, compliant with EU regulationsTotal length: 21.5 cmInsertion depth: 17.5 cmInner diameter: 2 cm (very flexible)Outer diameter: 8.3 cmColour: black case, natural interiorCompatibility: mystim Pure Vibes units (available separately)How to useApply a water-based lubricant to the inner sleeve. If you also want electrostimulation, connect the supplied adaptor cable to your mystim unit and always start on the lowest setting, then work your way up - the sensation of current can differ greatly from one person to another. The lubricant has a dual function here: it also improves conductivity, so don’t skimp on it. Always switch the current off before unplugging or repositioning the cables.What to bear in mind when using the mystim Opus E DonutYou need a separate unit for electrostimulation. The package contains the masturbator and the adaptor cable; the mystim Pure Vibes controller is not included - without it, it only works as a conventional masturbator.Must not be used in cases of heart disease, with a pacemaker or any other implanted electronic device, during pregnancy, or by people with epilepsy.
