If you're looking for variety, look no further. This vibrator comes with 10 functions, including multiple levels of constant vibrations, pulses, a mixture of the two, and escalating vibrations. All functions are great, and finding on that fits your style should not be an issue. My favorite function switches between the high steady vibrations, and one that includes fast pulses mixed with vibrations. To change modes, all one has to do is press the soft spot at the bottom of the toy. To turn the toy off, press the same button as mentioned, and hold it for about 3-4 seconds. This is definitely not the quietest toy in our collection. The level of the noise changes though, and it occasionally "flares" up and is quite loud. Turning the toy off and giving it a little nudge usually does the trick for us.
