If you are asking if it would be good for prostate stimulation, I would say no. For that you want something with a flared bottom, like a buttplug has. Otherwise there is a risk that it could go too far in, and you wouldn't be able to get it out. It has a pretty good vibe, but then most guys need a stronger vibe for their prostate. It's also not really ideally shaped for a prostate vibe.

As a g-spot vibe, I would say it's fair. Both the prostate and g-spot need strong stimulation, and this is not a really powerful vibrator. It's also not really long enough to combine thrusting motion with the vibration, which is what these spots love, in particular.

As a clitoral vibe, it's excellent. And that is what I use it for. It can also provide a nice counterpoint, when inserted, to another clitoral vibe.

It's got a really long cord, and this would be good for a partner who wanted to control a vibe stuck in some snug panties or otherwise held up to their partner. It's also pretty quiet, and so is less likely to make you burst out laughing at the noise or otherwise spoil the mood with angry hornet sounds.

Hope that helps less
