This is a toy we have used time and again to rev up the engine. I use this on her to get it going and it does its job admirably. We have had it for more than 3 years and it still works just fine. The plastic, however, is starting to change color in our toy drawer. That may be more due to our storage than age, but I don't know. I have a feeling more people than not store their toys incorrectly.

It has a single twist knob at the base that changes the vibration speed/intensity. When turned all the way up and inserted into her, I can feel the vibration on her pubic bone. It is dulled, but definitely there. It is a discreet enough size for travel yet obviously a sex toy, so don't let it tumble out of your bag if you are easily embarrassed!

It has a bulbous knob in the middle that, she tells me, sits just right where she wants it. Her one complaint is that she wishes it were a little longer at the curved point. It doesn't quite wrap around her g-spot, but more digs into it. As I don't have a vagina, I can't really say what this means!

She isn't into anal play, so I don't know how well it functions in that regard. Its shape tells me that it lends rather well for that or p-spot play but I'm not into that either. The other reviews make some mention of it for anal.

Overall, this toy gets her engine started and it has worked for three years. Now that I think on it, the only reason I'd replace it is cleanliness. We wash with soap and water and toss it in the drawer. Over time though, I have to think that the plastic starts to oxidize and deteriorate to the point that contaminants will begin to contaminate the vibrator. Maybe we will replace it, but only because of that!
