Great plug, only downside is the batteries don't last very long so suggest having spares on hand to avoid disappointment, otherwise highly recommended!
The only drawback is that it sticks out quite a way.
But it's a great you to leave in during sex as everyone feels the buzz.
We might have to get another one of these as there are arguments in the house as to who gets to wear it first. I love it up me and she goes off when it's up her. The good thing about this is that it's not a huge butt plug so I can double penetrative her while this is in her. It's awesome!
