Most vibrators contain a rotating offset weight. This design results in vibration of the whole vibrator, wasting most of the energy, and vibrating your hand. Tingletip is a high quality, precision engineered product, designed to vibrate directly at the point of contact. The tingletip head is the moving part, so all the power is delivered where it is most effective. This design makes tingletip even more effective than mains powered massagers, combined with the size and convenience of battery power. Tingletip is small and discreet, so much so that it can be left around the house without raising awkward questions from your mother, children, etc. Whereas some vibrators look like instruments of torture, tingletip is designed simply to satisfy. How do I use tingletip? To use, simply remove your electric toothbrush head and replace with tingletip massage head. If the clitoral area is dry, lubricant must be applied to the clitoral area before use. We recommend water based lubricants such as Durex Sensilube, although any are suitable. For maximum effect ensure that the electric toothbrush is fully charged. Which electric toothbrushes are compatible with tingletip heads? Tingletip is compatible with most Braun Oral B electric toothbrushes except Cross Action Power and Sonic Complete.
