The tip is a bit smaller than the shaft, with a diameter of 1 1/4". The shaft, right under the curve, is slightly thicker. Below that and right above the ring of nubs is the tickest, measuring a diameter of about 1 1/2". It has an insertable length of 5".
The control turn dial is at the bottom. It's pretty quiet when used from low to medium speed and gets a bit louder when turned up high but when inserted, you really can't hear it. It can be used with or without the vibrations.
I can think of many ways to use this but if you want to take advantage of the nubs, while using the toy, rub the nubs on your clitoris every time you withdraw it. You can also turn the vibrations up very high and use the tip just on your clitoris, without moving it at all, to have a clitorial orgasm.
I've experimented with this turned up to its highest speed and was able to have my first g-spot orgasm.
Babeland has a nice collection of vibrators in varying shapes and sizes, so there's something for everyone.
I received this from the company in exchange for an honest review.
