This is not a small head. At 103mm high, and 60mm wide, it is big, Eurasian crane big. It just happens to be about the same size as an average female fist.
A few notes on this large head.
1. It has an enormous surface area, each of the 3 segments hits hard. This head is the strongest feeling of all the heads to date.
2. It is big, my experience has been, after insertion - without warming up, it felt uncomfortably big, for the first 2-3 minutes. After the initial discomfort, it felt big.
3. The experience is unique and powerful, compared to something the the estim systems triple (medium), which is a large probe, it felt much stronger, bigger, and more comfortable.
One of the best ways to use the triple conductor is with an r3b. Corona channel to the bottom, Frenulum channel to the tip. If you have another channel available, the center of the head to the perinium pad, or the base of the probe.
