s a push button control on the very bottom, which is very easy to use. You will have to cycle through all functions to turn it off or get to the vibe you like the best. It comes with four different textured nubs that cap on top; two different sets with small spikes, a smooth rounded dome, and one with small flatter circles. I tried them all :) . The Travel Teaser has seven functions; It starts with a low continuous buzz, medium, then high. It has four pulsing settings. An escalating rhythm, short medium bursts, quick low bursts, then a succession of medium and high pulses. The high continuous setting has a pretty good, thrum to it.
The spiked caps seemed a little strange at first, and a bit intimidating. Ironically those were the most enjoyable. Because the hard plastic spikes were so different for me, so I started out gently, timidly, slowly adding more pressure which led to more pleasure. A completely separate time I used the smooth rounded cap, with a steady buzz, on DHs perineum which he fully appreciated. This toy is very user friendly, and is a great toy for the novice and experienced alike.
I should mention it is small enough to put in your purse or pocket with out attracting unwanted attention. Perfect for traveling!
I award The 7 Function Travel Teaser 4 out of 5 Hearts.
