Can be used alone or with a partner to enhance your sexual pleasure. It makes a bit of noise but this is to be expected with the powerful thrusting mechanism. I would prefer to have the maximum thrust & if that cums with a bit of noise it is fine.However this machine had moaning with pleasure so much I drowned out its little bit of noise. It’s a bit expensive but worth every dollar.A quality stimulating toy unlike any other. I highly recommend it !!
