I got this finger vibrator sex toy because I wanted my partner to have an easy way to play with me. So far, though, I've only used it on myself.The toy is made of smooth, durable silicone, which is my favorite material for sex toys (pleasant to touch and easy to clean). There are multiple vibration settings. Please note that I am pretty easy to please, so I usually just use a basic vibration setting. As a woman with average sized hands, the interior is a little large for my fingers, but it's manageable. It's not the thickest or longest toy, but it's enough to work with, and the round ball on the end does hit the "right place" when it's in use.My only complaint is that the ball that puts pressure in the "right place" is also where the power button and charging port reside (on either side of the ball). The device is fairly water-resistant, but I worry about my ability to clean the toy when the button and port get a little messy. I think if the ball was a bit bigger, this would be less of a concern. But overall, this toy has been effective for me, it's well-made, and I'd recommend it!
